摘要：

The low-energy states of the proton-rich nucleus Ge-62 were studied by the multinucleon knock-out reaction Se-67(C-12,X)Ge-62 using a C-12 target. The analysis of the Doppler-corrected singles spectrum of the gamma 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.
