Abstract：
High-spin states in ¹⁴¹Nd have been studied using in beam γ-ray spectroscopic techniques with the heavy ion induced ¹³⁰Te(¹⁶O,5nγ)¹⁴¹Nd reaction at 85 MeV beam energy. Nine anti Compton HPGe detectors were employed for the measurements of γ-ray singles and γ-γ coincidences. The previously reported ¹⁴¹Nd level scheme is significantly revised and extended up to much higher excitation energy. Spins for many excited states in ¹⁴¹Nd are tentatively assigned according to the measured γ-ray anisotropies. The level structure of ¹⁴¹Nd is interpreted by coupling a h_11/2 neutron-hole with the respective excited states in the ¹⁴²Nd core.
