Radiochemical Studies on the Fission ofTh232with Li+D Neutrons

The fission of ${\mathrm{Th}}^{232}$ with neutrons from lithium bombarded with 7.6-Mev deuterons has been investigated radiochemically. The relative yields of fourteen mass chains, mostly in the light group, have been determined. The yields of symmetrical products are about tenfold higher than in the fission of ${\mathrm{Th}}^{232}$ with pile neutrons. Very light mass chains (very asymmetric fission) show a much smaller increase in yield.
