Abstract
The study results of the \(d+{}^{1}\textrm{H}\to p+p+n\) reaction are presented. A kinematically complete experiment with using a deuteron beam energy of 15.3 MeV at the U-120 accelerator of the Skobeltsyn Institute of Nuclear Physics of the Lomonosov Moscow State University was carried out. A proton from the breakup of the singlet \(pp\) state and a secondary neutron were registered in coincidence. As a result of the study, the low-energy characteristics of \(pp\) interaction, namely, the energy value of the virtual singlet \(pp\) state and the corresponding value of the \(pp\) scattering length were determined.
