Abstract : During reactor operation (148g)Pm and (148m)Pm are formed in large quantities from thermal neutron capture on the fission product (147)Pm. Subsequent neutron capture reactions, on the (148)Pm ground state and isomer, have cross sections differing by a factor of 5 and so precise knowledge of their decay properties is vitally important. New decay scheme evaluations using the DDEP methodology for (148g)Pm and (148m)Pm are presented. The complete data tables and detailed evaluator comments are available through the DDEP website.
