Atomic parity nonconservative experiments in a number of elements have now achieved the level of precision necessary for significant tests of the physics of and beyond the standard model of electroweak interactions. In our laboratory, parity, nonconserving (PNC) optical rotation has recently been measured in both atomic lead and thallium at the 1% level of precision. The prospect of equally precise calculations of thallium atomic structure make this element an excellent candidate for a new low-energy test of electroweak physics. By studying hyperfine differences in thallium PNC, this experiment is also sensitive to nuclear spin dependent (anapole moment) effects at the level predicted by several models. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
