The decay of 67 hour 99Mo

Abstract

NaI(T1) and Ge(L1) detectors have been used singly and in coincidence to study the gamma rays associated with the decay of 67 h 99Mo Twenty-four of the twenty-eight observed transitions have been located by energy fit and by coincidence data, the remainder by energy fit alone The resulting decay scheme consists of levels at 140 5 ( 7 2 +) , 142 6 ( 1 2 −) , 181 1 ( 5 2 +) 509 1 ( 3 2 −) , 534 3, 671 5 ( 5 2 −) , 761 6 ( 5 2 +) , 920 5 ( 3 2 +, 1 2 +) , 1004 0 ( 3 2 −) , 1072 9 ( 5 2 −) , 1129 3 ( 1 2 −, 3 2 −) , 1142 0 3 2 −) , 1199 ( 1 2 −, 3 2 −)
