摘要: Abstract The gamma-ray transitions following the 108Pd(α, 2n) reaction have been observed using different semiconductor detector systems, including a Compton suppression spectrometer. Approximately 200 assigned to 110Cd were identified in energy range 120 1600 keV. About 2.5 × 107 γγ-coincidence events recorded and angular distributions of most analyzed. level scheme was extended by 28 new levels. With distribution results systematic use excitation slopes side-feeding intensities (ESSI-method), spins parities nearly all levels determined. regarding ground-state, intruder octupole bands are interpreted framework s-p-d-f interacting boson model which mixing is explicitly included. predictions strong configuration also examined detail neutron-proton framework. We shortly discuss possible non-collective, broken-pair excitations qualitative way.
