Reaction cross sections in the interactions of neutrons with Yttrium nucleus

Abstract

In this research, the cross sections of the nuclear reactions Y-88(n, 2n)Y-87, Y-89(n, 2n)Y-88, Y-89(n, 3n)Y-87, Y-89(n, p)Sr-89, Y-89(n, d)Sr-88, Y-90(n, 2n) Y-89 and Y-90(n, p)Sr-90 have been calculated using advanced nuclear models at incident neutron energies up to 40 MeV. The theoretical values of nuclear cross sections for these reactions have been estimated by the computer codes ALICE-ASH, PCROSS and CEM03.01. Effect on the cross sections of level density parameters used in the calculations has also been discussed. Finally, the excitation function systematics have been observed with a significant contribution to obtain the nuclear cross sections for bombardment energy range of 14-15 MeV.
