Levels: In analogy with neighboring odd-mass nuclei one expects for Z=97 configuration=(π 3/2[521]) (from 245Bk, 247Bk, 251Bk) and for n=149 configuration=(ν 7/2[624]) (from 243Pu, 245Cm). This combination should give two states with Jπ=2- and with Jπ=5-, respectively, the latter being of lower energy (Gallagher-Moszkowski rule). Another possible configuration=(π 7/2[633]) (from 249Bk) and configuration=(ν 7/2[624]) would give 7+, 0+ states. 1987So10 predict the occurrence of 2- and 0+ states in this nuclide.
