States in 152Sm populated by the (t,α) reaction

Levels in the deformed even-even nucleus 152Sm have been populated by the (t,α) reaction using beams of 15 MeV tritons. On the basis of levels observed in adjacent odd-Z nuclei and some previous (α,2nγ) results, a rotational band built on the Ksup(π) = 5-, 5/2+[413] + 5/2-[532] two-quasiparticle state has been identified. A Coriolis coupling calculation has been done, which gives good agreement with experimental energies and cross sections when an attenuation factor of 0.31 is used for the Coriolis matrix elements.
