This paper reviews the achievements of nuclear physics for various fields of knowledge and unique technologies in the sectors of the world economy. It is difficult to imagine modern society without the achievements of nuclear physics. It is also one of the driving forces for the development of our civilization.
Counting back to the first nuclear reaction carried out, which is more than a...
The Nuclotron-based Ion Collider fAcility (NICA) is the flagship project at the Joint Institute Nuclear Research (Dubna, Russia). Two goals of the project — experimental studies of dense nuclear (baryonic) matter and particle spin physics — are combined in the project on the basis of a common experimental method: the investigation of collisions of nuclei at relativistic energies. The project...

The microscopic theory of atomic nuclei now spans energy scales from kilo-electron-volts to giga-electron-volts. The leading degrees of freedom for prominent experimental phenomena range from clusters or collective modes of nucleons to quarks and gluons. Many profound questions can be raised. Is there harmony across scales? Are there emergent phenomena at one scale that trace their origins to...
Asymptotic normalization coefficients (ANC) determine the asymptotic behavior of nuclear wave functions in binary channels at distances between fragments exceeding the radius of nuclear interaction (see the recent review paper [1] and references therein). ANCs are of particular importance for nuclear astrophysics. They determine the overall normalization of cross sections of radiative capture...
SKIF is the Russian acronym for Siberian Circular Light Source – a new fourth generation synchrotron light facility that is now under development in Novosibirsk (Russia). SKIF consists of 200 MeV linear accelerator-preinjector, 3 GeV booster synchrotron (154 m in circumference), 3 GeV electron storage ring (476 m) with extremely low natural horizontal emittance of 73 pm⋅rad and number of...
We present a selection of very recent results by the CMS collaboration on heavy-ion physics at the LHC (CERN).
Jiangmen Underground Neutrino Observatory is an experiment under construction in China. A spherical detector of 35 m in diameter filled with 20 kt of liquid scintillator and equipped with more than 17'612 (25'600) large (small) photomultipliers will provide immense statistics, high energy resolution (σ=3% at 1 MeV) and low energy threshold (0.2 MeV) making the physics program broad.
The...
The recent experiments on Compton scattering using a new experimental technique [1] gave rise to a new wave of interest in this old effect discovered 100 years ago. To describe the process of Compton decay of positronium we use the nonrelativistic A2 approximation.
We study the Compton single ionization of positronium in comparison with the same of hydrogen [2]. The initial photon...
A low-energy magnetic dipole (M1) spin-scissors resonance (SSR) located just below the orbital scissors resonance (OSR) was predicted in deformed nuclei within the Wigner function moments (WFM) approach, see [1,2] and references therein. We analyze this prediction for 160,162,164Dy and 232Th using fully self-consistent Skyrme quasiparticle random phase approximation (QRPA) method [3]. Accuracy...
I show that in a strongly interacting plasma, the fluctuations responsible for deviations from those of a description based on a simple Hadron Resonance Gas Model naturally arise from the proper inclusion of the plasma screening properties. These are encoded in the contribution of the so called "ring diagrams" and thus in the introduction of a key feature of plasmas near phase transitions,...
Studies of genuinely nonperturbative nucleon resonances (N) structure in exclusive electroproduction off protons shed light on emergence of the dominant part >98% of hadron mass which is one of the most important and still open problem in the Standard Model. [1]. The current status of the N electroexcitation studies in connection with the insight into strong interaction dynamics in the...
Particle-Hole Dispersive Optical Model (PHDOM) has been originally proposed [1] and then implemented to describing main properties of various isoscalar and isovector giant resonances (GRs) in medium-heavy closed-shell nuclei (see, e.g., Ref. [2] and references therein). Main properties include the energy-averaged strength distribution, transition density, and probabilities of direct...
For even-even nuclei, with the exception of the only, in yrast bands there is no manifestation of the reverse bending of the moment of inertia from the square of rotation frequency (back-bending). This leads to the possibility of reproducing the level energies of yrast bands up to spins values in the framework of the IBM1 phenomenology [1]. In present report the structure of the yrast band...
In the talk will be done a review of suggestions for experiments with usage of the Spin Physics Detector (SPD) at the first stage of the NICA SPD Programme developing in JINR [1]. Double polarized pp, dd and pd collisions at c.m.s. NN energies of 3-10 GeV, which will be accessible at the initial stage of the planned experiments, allow one to study spin dependence of the NN...
The nuclear shell model is one of the oldest microscopic approaches to nuclear structure at low energies [1,2]. The basic idea of the method is to solve the many-body Schrodinger equation by diagonalizing the Hamiltonian, containing nucleon kinetic energies and internucleon interactions, in the many-body harmonic-oscillator basis. Because of the rapid increase of the model space with the...

The strong dependence of the correlation between energy and angular distributions of the observed alpha-particles in heavy ion collisions on the beam energy shows the importance of the impact parameter in the incomplete fusion [1,2]. The complete fusion of the interacting nuclei is transfer of all nucleons in light projectile to the target nucleus. This process may be hindered by the intrinsic...
The $\beta$-decay strength function $S_{\beta}(\textit{E})$ governs [1-3] the nuclear energy $\textit{E}$ distribution of elementary charge-exchange excitations and their combinations like proton particle $({\pi}p)$-neutron hole $({\nu}h)$ coupled into a spin-parity $I^{\pi}$: $[{\pi}p \otimes {\nu}h]I^{\pi}$ and neutron particle $({\nu}p)$-proton hole $({\pi}h)$ coupled into a spin-parity...
To describe the γγ-decay, a formalism relates the electromagnetic interaction up to second order in the electromagnetic operators and two-quantum processes in atomic nuclei. In Ref.[1], the γγ-decay of a nuclear transition in competition with an allowed γ-decay has been discovered. This is the observation of the γγ-decay of the first excited $J^{π}$=$11/2^-$ state of $^{137}$Ba directly...
The cross section for a reaction of nuclear fission induced by polarized neutrons can be represented [1] as the sum of the cross section for the reaction with unpolarized neutrons, where is the angular distribution of such light particles p as prescission -particles and evaporative neutrons and -quanta, and the cross section , which depends linearly on the polarization vector and is...
In the near future, the BM@N experiment at the Nuclotron at JINR in
Dubna will start a physics program with heavy ions including Au-beams at
energies up to 3.8 A GeV and intensities up to 2⋅10^6 ions/s. The
experiment is devoted to measure observables sensitive to the equation
of state of dense baryonic matter, and to search for indications of a
phase transition at high densities. To meet...
The neutrino dynamics in hot and dense matter corresponding to supernova explosions is considered. The kinetic equation for a neutrino phase-space distribution function is obtained, taking into account inelastic scattering by nuclear particles. The transfer and diffusion components in an energy space are argued to dominate in the transport properties. It is shown that the energy transfer...

In modern nuclear medicine the main clinical information is obtained from observing the radiopharmaceuticals (by incorporating a radionuclide into the pharmaceutical) distribution in the patient body. These pharmaceuticals are a mixture of a biochemical agent and a radionuclide that emits gamma quanta or positrons [1]. Diagnostic imaging with single-photon-emitting radionuclides produces both...
In a wide range of characteristics of the corpuscular radiation of the near-Earth outer space, protons dominate (more than 90%), which have a high penetrating power and cause radiation damage and upset the onboard electronics (OBE) of the spacecraft. The nature of failures can be either degradation of the initial characteristics of OBE elements with increasing radiation dose, or a failure as a...
