Proposed measurement of the anapole moment in francium

Summary form only given. The anapole moment of a nucleus is a parity nonconserving, time reversal conserving moment that arises from weak interactions between the nucleons. It can only be detected in a PNC electron-nucleus interaction. We study an earlier suggestion of directly measuring the probability of E1 transitions between the ground hyperfine states of an atom, allowed only through the anapole moment, with the present possibilities of atom manipulation.
