摘要：

Excited states in Ra-219 were studied by means of the Pb-208(C-14,3n) reaction at 65 MeV. The investigation was made with 12 Compton-suppressed Ge detectors and a multicounter array. Transitions in Ra-219 were selected by requiring appropriate conditions on fold and sum energy. The proposed level scheme shows two sidebands with alternating parity structure decaying to the ground-state band. It is consistent with a recent description of Ra-219 in the framework of the reflection-asymmetric mean-field approach, which predicts a K = 1/2 ground-state band and two low-lying bands with quantum numbers K = 3/2 and K = 5/2.
