An earlier work dealing with shape coexistence for even-even nuclei is exte
nded to treating odd-mass nuclei including proton excitations across dosed
shell. With the approach, energy spectra and some E2 transition branching r
atios are calculated for odd-A nuclei Sb-113 similar to 125, I-115 similar
to 127. The theoretical results give a good reproduction to the experimenta
l data.
