Description

Interaction in two-neutron system (2 n) in the reaction T (d, 3 He) at energy Ed = 31 MeV has been experimentally investigated. In the angular range from 6 deg. up to 13 deg. with large transverse cross section nuclear nonstable 2 n is observed with decay width Γ = (1.1 ± 0.2) MeV. In 3 He nuclei spectra two wide energy resonances are found. Assumption about excitation in n-n system wide resonances with energies Ε* = (3.6 ± 0.3) and Ε* ∼ 11.8 MeV, populated in the reaction T (d, 3 He), is made
