Rotational states in 151Nd populated through thermal neutron capture

The level scheme in the nucleus 151Nd has been studied following neutron capture by observing the γ-rays and conversion electrons with curved-crystal spectrometers, a Ge(Li) detector and a β-spectrometer. A comprehensive level scheme up to approximately equal to 1 MeV was established. It is shown that the present level scheme energies differ from those previously found in a 150Nd(d,p) reaction study by a systematic shift of 27 keV. The binding energy of the last neutron in 151Nd was deduced. For most levels spin and parity values are proposed and an identification of bands with Nilsson-model configurations is given. (Auth.)
