Study of ¹⁵¹Eu levels via the (p,2nγ) reaction

Gamma rays from levels in ¹⁵¹Eu have been studied following the ¹⁵²Sm (p,2n) reaction. A level scheme based on excitation functions, on angular distributions and on prompt and delayed gamma - gamma coincidence measurements is proposed and compared with findings by other authors. Some transitions observed lead to levels not previously compared with findings by other authors. Some transitions observed lead to levels not previously identified in gamma -ray work. The experimental results are compared with the predictions of the rigid rotor-plus-particle model including Coriolis coupling. Negative-parity states are described in terms of the interacting-boson model.
