Abstract

Excited states of Pm151 have been observed using the Nd150(,p2n) reaction at a beam energy of 35 MeV. Levels with spin up to 19/2 have been seen in a positive parity band built on the 5/2+ ground state, and up to 21/2 in a negative parity band built on the 5/2- level at 117 keV excitation energy. Levels of the same spin but opposite parity are nearly degenerate and there are strong (1.1×10-3 W.u.) electric dipole transitions between members of the two bands. The energy staggering of levels and their electromagnetic decay properties are somewhat different for the two bands.
