Off-diagonal hyperfine interaction and parity nonconservation in cesium
Off-diagonal hyperfine interaction and parity nonconservation in cesium
We have performed relativistic many-body calculations of the hyperfine interaction in the $6s$ and $7s$ states of Cs, including the off-diagonal matrix element. The calculations were used to determine the accuracy of the semiempirical formula for the electromagnetic transition amplitude $〈6s|M1|7s〉$ induced by the hyperfine interaction. We have found that …
