Levels: Band assignments are from 246Am (25 min) decay. They are from 1976Mu03 and include assignments from other references. The band parameters (Eo in keV, α in keV and B in eV) have been calculated here from the equation E=Eo + AJ(J+1) + B[J(J+1)]2 using the three (or two) lowest members of the band.

Levels: See (d,d’) for B(E3) values of the negative parity bands.

Q-value: Note: Current evaluation has used the following Q record
