Observation and cross-section of the reaction Zn64(n, t)Cu62

Abstract

We eonfirmed the existence of ZnS~(n, t)Cu 62 reaction and determined its eross-seetion as 150pb+lOpb at 14,7 MeV neutron energy. A quick chemical separation technique enabled the measurement of the weak Cu 62 activity. The relatively high yield of the (n, t) reaction cannot be explained on the basis of the statistical model.
