Experimental moments of inertia in Pd and Cd isotopes and their interpretation within the extended Nilsson-Strutinsky model

High-spin properties of even Pd and Cd isotopes have been studied by means of a 118 MeV 12C beam impinging onto a 100Mo target. The γ-rays following the reaction were recorded using six NaI(Tl) detectors in a two-dimensional coincidence arrangement. Energy-correlation spectra were extracted from the coincidence matrix and used to obtain information on the collective moment of inertia circular integralsup((2)). The gross properties of the behaviour of this moment of inertia are discussed within an extended Nilsson-Strutinsky model. The experimentally observed variation of the moment of inertia at high rotational frequencies is tentatively explained as being due to an increase of circular integralsup((2))sub(band) as the band approaches its termination.
