Popis: | Hyperfine mixing in a weak magnetic field gives rise to new interference terms between the Stark-induced amplitudes of the 6S–7S forbidden transition of cesium. Compared with typical allowed transitions, effects of unusual size (circular dichroism of ∼10% in a 10 G field) and/or symmetry (3% upper state spin polarization induced by linearly polarized light in a direction normal to both the beam and the magnetic field) are observed. The circular dichroism yields a new method to determine the scalar to vector polarizability ratio; our result (α/β=-10.0±0.15) agrees with those of other techniques. The analysis of systematic effects in our recent measurement of parity violation required an understanding of these hyperfine mixing effects. One of them will be utilized to calibrate a new version of the parity experiment. |
