Description

A value of a neutron-neutron scattering length was obtained in different experiments. It can be observed that there is a spread in values of a neutron-neutron scattering length $a_{nn}$. In [1] it was suggested that such spread may be explained by influence of 3$N$-forces. It can be assumed that pp-scattering length and energy of $^{1}S_{0}$ virtual state extracted in the $d + ^{1}H → n + p + p$ reaction will be influenced by 3$N$-forces and will differ from the value obtained in the experiment with two protons in a final state. To test the assumption, in INR RAS the study of the $d + ^{1}H → n + p + p$ reaction is carried out.
In current work a processing of data from several measurements to study the $d + ^{1}H → n + p + p$ reaction with registration of protons from the breakup of a $pp$-system and a recoil neutron is discussed. The proton energy spectrum was obtained in these measurements. A comparison of obtained experimental spectrum with the simulated ones that correspond to different values of virtual $pp$-state energy was carried out. As the comparison result the estimation of possible value of proton-proton energy state was done.
