Low-lying excited states in 62 Ge investigated by multinucleon knock-out reaction

The low-energy states of the proton-rich nucleus 62 Ge were studied by the multinucleon knock-out reaction 67 Se( 12 C,X) 62 Ge using a 12 C target. The analysis of the Doppler-corrected singles spectrum of the γ rays showed two transitions at 744(20) keV and 948(17) keV, which were found to be in c...

Zusammenfassung:	The low-energy states of the proton-rich nucleus 62 Ge were studied by the multinucleon knock-out reaction 67 Se( 12 C,X) 62 Ge using a 12 C target. The analysis of the Doppler-corrected singles spectrum of the γ rays showed two transitions at 744(20) keV and 948(17) keV, which were found to be in coincidence with each other, forming a cascade and establishing two states at 948(17) keV and 1692(26) keV. The 744 keV transition was detected for the first time, and based on a comparison of the experimental data to shell-model and symmetry-conserving-configuration-mixing-model calculations, it connects the second and first 2 + levels. The beyond-mean-field model suggests that these states belong to two different bands with triaxial features and similar deformation.
