Jπ(level): g.s. Jπ=(5/2+) assigned on the basis of systematics (1996Ur02). This assignment is consistent with a expected (11/2-) bandhead deexcited by E1 and E2 cascade to g.s.. Other Jπ assigments are based on interconnecting M1 or E2 transitions and rotational band arguments from 248Cm SF decay and 252Cf SF decay.
