INTERACTING BOSON MODEL FOR EVEN-EVEN NUCLEI POSSESSED OF 1+ AND 3+ BANDS IN THE ROTATIONAL RIGION

  • On the bases of s, d IBM, octupole states are taken into account and the two-quasiparticle excitation is treated as boson-like in the SU(3) limit. The energy spectra are obtained analytically and the nondegenerated 1+ and 3+ bands are also reproduced. The calculated spectra of eight nuclei, which possess with 1+ or 3+ bands in their energy spectra in the rotational rigion, agree with the experimental ones fairly good.

INTERACTING BOSON MODEL FOR EVEN-EVEN NUCLEI POSSESSED OF 1+ AND 3+ BANDS IN THE ROTATIONAL RIGION

    Corresponding author: ZENG Jia-Gang,

Abstract: On the bases of s, d IBM, octupole states are taken into account and the two-quasiparticle excitation is treated as boson-like in the SU(3) limit. The energy spectra are obtained analytically and the nondegenerated 1+ and 3+ bands are also reproduced. The calculated spectra of eight nuclei, which possess with 1+ or 3+ bands in their energy spectra in the rotational rigion, agree with the experimental ones fairly good.
