Reduced Sputtering Yields Induced by Fast Neutrons
Chin. Phys. Lett. 1999, 16 (11):
The reduced sputtering yield (yRn) of materials induced by fast neutron is presented. Based on the experimental yRn results for (n, 2n), (n, p), (n, α) and (n, np) reactions, the value of yRn for (n, non-elastic) reaction is deduced by using data of cross sections in JENDL-3.2 and ENDF/B-VI. The value of yRn for (n, n) reaction is predicted by relation between yRn and the mean projected ranges of recoil nuclides. Combining both yRn for (n, n) and (n, non-elastic) reactions, the total yRn is obtained. Systematics of yRn for (n, non-elastic), (n, n) and (n, total) reactions have been demonstrated.
