Abstract

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.
