Abstract
A high-precision experiment to measure parity-nonconservation in atomi c Yb has been proposed recently [D. De Mille, Phys. Rev. Lett. 74, 416 5 (1995)]. We use a relativistic configuration-interaction approach to highlight the importance of correlation effects in the 6s(2)(S-1(0))- ->6s5d(D-3(1)) parity-nonconserving electric transition amplitude for Yb. Our result shows that this transition amplitude is dramatically al tered by the strong mixing between some of the configurations that mak e up the odd-parity 6s6p(P-1(1)) atomic state.
