摘要：

An in-beam gamma-ray study performed with the Sb-121 (F-19,4n) reaction has established the high spin level structure of the N = 78 nucleus 138Nd. States up to I = 21hBAR and 8.5 MeV excitation energy have been identified. High spin states are described in the framework of the cranking model and of the interacting boson model with broken pairs. The calculations reproduce levels up to I = 18hBAR including the two 10+ states which, from the feeding cascades, are identified as the nuh112(-2) and pih11/2(2) excitations. Cranked Strutinsky type calculations predict opposite shapes for the two different types of excitations.
