CROSS-SECTIONS OF NEUTRON REACTIONS ON TARGETS IN THE GROUND AND ISOMERIC STATES

The results of theoretical calculations of the cross sections for the (n, gamma), (n, n'gamma), and (m 2n) reactions on targets in high-spin isomeric states corresponding to long-lived states of nuclei are pres ented. It is shown that an increase in the energy of an isomeric state leads to a displacement of the excitation function toward lower energ ies, while an increase in the isomer spin noticeably increases the cro ss section of the (n, n'gamma) reaction in the threshold region, and a ccordingly, reduces the cross section of the (n, 2n) reaction.
