A recent treatment of first-forbidden {beta}{sup {minus}} decay in the lead region is extended to {beta}{sup +} decay and electron capture. The modified Kuo-Herling shell-model interaction recently described by Warburton and Brown is used to calculate wave functions and observables for {sup 211}Po. The log{ital f}{sub 0}{ital t} values for the {sup 211}Bi(9/2{sup {minus}}){r arrow}{sup 211}Po(9/2{sup +}) {beta}{sup {minus}} transition and the electron capture of {sup 211}At(9/2{sup {minus}}) into the 9/2 {sub 1}{sup +} and 11/2 {sub 1}{sup +} states of {sup 211}Po are predicted to be 6.008, 5.891, and 5.850 as compared to the experimental values of 6.026{plus minus}0.017, 5.960{plus minus}0.008, and 5.831{plus minus}0.090, respectively. The wave functions and spectrum of {sup 211}Po are calculated in the Kuo-Herling model space. The yrast spectrum is presented for comparison to anticipated results from fusion-evaporation reaction studies. The experimental {sup 210}Po({ital d},{ital p}){sup 211}Po spectroscopic factors are quite accurately reproduced.
