Two experiments are currently underway to measure the single-particle weak mixing matrix element for the 1064 KeV transition in {sup 207}Pb. One experiment measures the circular polarization of the 1064 KeV gamma ray emitted from an unpolarized source, while the other experiment measures the forward-backward asymmetry of gamma rays emitted from a polarized source. Analysis of the first set of polarized source data yields an upper limit of 46 eV for the single-particle weak mixing matrix element. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
