Experimental setup for studying N–N correlations in reaction d + 2H → n + n + p + p

Resumo

An experimental setup for studying the effects of N–N correlations in reaction d + ²H → n + n + p + p is described. It is planned to determine the energies of quasibound singlet states of two-nucleon systems (nn, pp, and np) under identical experimental conditions. The experiment is modeled numerically. The setup allows us to detect simultaneously the two nucleons (n + n, p + p, or n + p) resulting from the breakup of a quasi-bound state and a third particle (n or p). The characteristics of the setup’s detectors are investigated. A test experiment was carried out on reaction d + ²H → (pp) + (nn), with two protons and a neutron being detected.
