Particle-core coupling in 141Nd

High-spin states in 141Nd have been studied using in-beam γ-ray spectroscopic techniques via the 130Te(16O, 5nγ)141Nd reaction. The level scheme of 141Nd has been extended up to an excitation energy of 7614.5 kev including 12 new γ rays deexciting 15 new levels. According to particle-vibrator coupling and semi-empirical shell model calculations, the level structure of 141Nd can be well interpreted by coupling an h11/2 neutron-hole to the respective excited states in 142Nd core.
