Ay. Konobeyev et al., SEMIEMPIRICAL SYSTEMATICS FOR (N,ALPHA) REACTION CROSS-SECTIONS AT THE ENERGY OF 14.5 MEV, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 108(3), 1996, pp. 233-242
A new semi-empirical 7-parametric formula for the calculation of (n, a
lpha) reaction cross sections at an energy of 14.5 MeV is suggested. T
o derive it the analytical expressions describing the alpha-particle e
mission spectrum within the frame of the pre-equilibrium exciton and t
he evaporation models were used. The systematics obtained ensures bett
er agreement with experimental data than empirical systematics suggest
ed earlier by other authors.
