| dc.description | An experimental study has been made of the nearly degenerate, opposite parity states 4f <sup>6</sup>6s6p <sup>7</sup>G<sub>1</sub> and 4f <sup>6</sup>5d6s <sup>7</sup>G<sub>1</sub> in samarium to assess the feasibility of using the forbidden M1 transition from the 4f <sup>6</sup>6s <sup>2</sup> <sup>7</sup>F<sub>0</sub> ground state to the 4f <sup>6</sup>5d6s <sup>7</sup>G<sub>1</sub> state for measuring parity non-conserving (PNC) effects. The authors conclude that detection of the PNC optical rotation is not feasible because of the high background rotation present at the M1 wavelength and also because the PNC signal itself would be significantly smaller than in existing PNC experiments. Consideration has also been given to the possibility of a novel optical rotation experiment on this transition, using crossed electric and magnetic fields. However, this too is concluded not to be feasible due to the difficulty in achieving a sufficiently large PNC signal. A general comment on the future of rare earth elements for PNC studies is made. |
