MICROSTRUCTURE ON COLLECTIVITY IN EVEN ^116-122Xe ISOTOPES

Using microscopic interacting boson-fermion model formalism, the ground-band, \beta-band, \gamma-band and high spins states in even ^116-122Xe isotopes are successfully described. It can explain the recent experimental result that collective structures may coexist with the single-particle states and subshell feature. It predictes the energies of 1⁺ states.
