The {beta}{sup {minus}} decay of {sup 136}I isomers to levels in {sup 136}Xe was studied using sources isolated at the on-line mass separator TRISTAN. Conversion-electron and gamma-ray singles data have been collected. Evidence for excited O{sup +} states at 2582.4 and 4320 keV has been obtained. A shell-model study elucidating the salient features related to the first excited O{sup +} state in the {ital N}=82 nuclei has been carried out. Comparing two-particle, four-particle exact shell-model and two-quasiparticle shell-model calculations using both a Gaussian and surface-delta interaction in the latter case, an explanation could be given for the {ital Z} dependence in the {ital E}{sub {ital x}}(O{sub 2}{sup +}) excitation energy. We also calculate the {ital E}0 reduced matrix elements for {sup 134}Te.
