The shape of the angular distribution for 550+570 group is consistent with L=4+5, J=6, Kπ=5- and 6+, but the total measured cross section is larger than the predicted value. Probably there are additional levels in this energy region.

E(level) | E(gamma) | Comments |
39.10 | 39.0 | M(γ): from intensity balance at 39 level in 162Gd β- decay, transition is primarily M1 (1970Ch02); x/γ intensity ratio and L x-ray energy are consistent with this. |
