Shape coexistence in the Ru isotopes; multi-spectroscopic study of 98Ru and beyond-mean-field calculations

Acta Physica Polonica B, Volume 51, No. 3, Year 2020

The level structure of 98Ru was investigated via γ-ray spectroscopy following the β+/electron capture decay of 98Rh and with the 100Ru(p; t)98Ru reaction. Additional γ-ray transitions from low-lying levels were observed and spin-parity assignments of some key states were clarified, permitting the assignment of the 0+2 band and the γ band. The energies of the states in these bands fit well into the systematic trends observed in the heavier isotopes. The results are interpreted with the aid of beyond-mean-field calculations performed within the self-consistent configuration mixing method.
