摘要
The energy spectra of the parent and daughter nuclei in the beta decays ((121-127)Xe,beta(+121-127)I) are considered in the interacting boson fermion model (IBFM-2) with the g(7/2),d(5/2),d(3/2),s(1/2), and h(11/2) single-particle orbitals. Electromagnetic transition probabilities and branching ratios in odd (121-127)I isotopes are investigated. Special attention is given to the occurrence of mixed symmetry states, and the F-spin structures of the wave functions are analyzed. The log(10)ft values of the allowed beta decay transitions are calculated. It is found that the IBFM-2 results agree with the experimental data quite well.
