Description of Yrast States in \({}^{{76}}\)Ge

Systematic calculations of low-lying energy levels and \(B(E2)\) transitions in the \({}^{76}\)Ge nucleus are performed by diagonalization of the five-dimensional Bohr collective Hamiltonian with the microscopic input derived from a self-consistent mean-field calculation based on the multidimensional constrained covariant density functional theory. The relativistic functionals PC-PK1, NL3, and NL3\({}^{\ast}\) supplemented by a finite-range pairing force are used. The calculated properties of the yrast band show good agreement with available experimental data. Based on the analysis of energies of yrast states and the \(B(E2)\) branching ratios the \({}^{76}\)Ge isotope is a viable candidate for an asymmetric rotor description with \(\gamma=30^{\circ}\).
