Parity-violating circular dichroism in atomic caesium (neutral currents)

Abstract
The parity-violating E1 transition matrix elements between the 6s and 7s states of atomic Cs to be expected on the basis of the Weinberg-Salam model of neutral weak currents has been calculated. It is found that iE16s,7s=3.60*10-11 atomic units, in excellent agreement with a calculation by Bouchiat and Bouchiat (1975) using a different method.
