New atomic parity nonconservation (PNC) experiments will be             carried out using Thallium and the rare earth elements erbium,                  samarium, gadolinium, and perhaps dysprosium.  Very large                       improvements in signal are possible over those obtained in                      previous experiments, by means of the proposed techniques:                      hypersonic beams, Stark interference, pulsed laser spectroscopy,                and ionization detection.  It appears feasible to measure quite                 accurately nuclear spin dependent PNC effects, and the                          possibility exists for a good measurement of Weinberg's angle                   from a comparison of PNC asymmetries.  Such a comparison may also               be possible in different isotopes of the rare earths.  The                      results of such comparative measurements would be nearly                        independent of uncertainties in Stark.induced electric.dipole                   matrix elements and in atomic theory.
