“…Study of the high spin states in this region can provide important insight into the nuclear structures [1]. Previously, the high spin collective band structures in even-even 108,110,112 Ru have been studied by measuring the prompt γ-rays emitted from the spontaneous fission or the induced fission of heavy nuclei [2][3][4][5][6][7][8][9][10]. Besides the ground state bands, some collective bands such as onephonon and two-phonon γ-vibrational bands, and chiral doublet bands have been observed in 108,110,112 Ru.…”
