Abstract

The level structure of the even-even 112Cd nucleus was investigated by means of the 110Pd(α, 2nγ) reaction spectroscopy. On the basis of the γγ-coincidences measured using three Compton-suppression spectrometers, 151 transitions (out of 190 lines assigned to 112Cd) were placed in the decay scheme. Most of the 80 observed excited states were grouped into 6 well-developed collective bands. The level scheme was extended by 43 new levels. The systematic use of the excitation function slopes and of the side-feeding intensities, together with the results gained from the angular distribution allowed us to assign the spins and the parities to nearly all observed levels. The collective states, including in particular those of the ground-state, intruder, quasi-γ and octupole bands, and their electromagnetic properties were investigated in the framework of the spdf 1BA-1 model with configuration mixing of normal and intruder states.
