It is reported that 69Ga (n, 2n) 68Ga, 69Ga (n, p) 69mZn measured by the 93 Nb (n, 2n) 92mNb reaction cross section as a neutron fluence metric in the 13.5-14.6 MeV neutron energy region , The cross-sectional values of 71Ga (n, p) 71mZn and 71Ga (n, n’α) 67Cu were calculated from the ranges of (13.5 ± 0.2), (14.1 ± 0.1 and 14.6 ± 0.2 ) 69Ga (n, 2n) 68Ga reaction cross section of MeV neutron are (794 ± 31), (86 9 ± 35) and (986 ± 39) mb, (1.3 ± 0 .1), (1.7 ± 0 .1) and (2.5 ± 0 .1) mb, respectively. At neutron energies of (14.1 ± 0.1) MeV, 69Ga (n , p) 69mZn The cross section of the reaction is (2 1.5 ± 1.0) mb and the reaction cross section of 71Ga (n, p) 71mZn is (12.4 ± 0.77) mb. He obtained the reaction.The article also lists the data collected as much as possible for comparison.
