DESCRIPTION:Speakers: I. Solovyev (NRC Kurchatov Institute PNPI)\nThe ther
 monuclear reaction $d({}^3\\!He\,\\alpha)p$ is a very rich playground to s
 tudy various phenomena in different fields of science. Astrophysicists use
  data of the cross section to build and tune a theory of primordial nucleo
 synthesis. Most nuclear reactions data doesn’t contain energy dependenci
 es below several keV\, the most interesting region for astrophysics.\nFrom
  a practical point of view\, the reaction is extremely efficient in energy
  generation. While producing 18.3 MeV worth of energy\, one of the highest
  energy outputs among nuclear reactions\, it doesn’t contain nor produce
  radioactive elements. It makes possible the construction of the safest an
 d efficient thermonuclear reactor.\nThe use of muons expands studies even 
 more. It makes possible to investigate the reaction at extremely low energ
 y (several eV) that has never been done before. Bombarding a gas mixture o
 f $^3\\!He$ and $D_2$ ($H\\!D$) with energetic muons results in the format
 ion of exotic muonic molecules such as $^3\\!He\\mu d$. It was theoretical
 ly shown [1] that $^3\\!Hed$ fusion can occur in this formation.\nThe expe
 riment\, aimed to investigate muon catalyzed $^3\\!Hed$ fusion\, is being 
 carried out at PSI (Switzerland) by the PNPI group (Gatchina\, Russia). It
  enables the study of processes involving mesomolecules.\nThe experimental
  setup\, adopted from the previous experiment MuSun [2]\, includes the cry
 ogenic TPC\, muon beam detectors\, kicker and detection system of electron
 s coming from muon decays. The kicker allows muons to enter the fiducial v
 olume only one by one. The data collected enables to determine a muon stop
  position\, detect tracks of electrons created via the muon decay as well 
 as tracks of fusion products. Information about the energy of each particl
 e is also obtained.\nThe formation rates of the $d\\mu d$ and $^3\\!He\\mu
  d$ molecules\, the probability of the muon transfer from $\\mu d^*$ to $\
 \mu d$\, the upper limit for the “effective” $^3\\!He\\mu d$ fusion de
 cay rate\, yields of $^3\\!He\\mu d$ molecules have been obtained and pres
 ented.\n\n1. M.P. Faifman and L.I. Men'shikov\, Hyperfine Interact. 119\,
