Abstract: | The hyperfine structure of the metastable atomic states (3d 44s 2)5 D 1,2,3,4 of53Cr has been measured using theABMR-LIRF method (atomic beam magnetic resonance detected by laser induced resonance fluorescence). The dipole coupling constantsA and the quadrupole coupling constantsB are found to beA(5 D 1)=?17.624(2) MHzB(5 D 1)=?21.847(5) MHzA(5 D 2)=?25.113(2) MHzB(5 D 2)=?13.485(5) MHzA(5 D 3)=?35.683(2) MHzB(5 D 3)=15.565(5) MHzA(5 D 4)=?48.755(2) MHzB(5 D 4)=63.021(5) MHz. From these measured hfs constants the electric quadrupole moment for53Cr is calculated to beQ=?0.15 (5) barn. The 30% error takes into account the uncertainties due to configuration interaction effects (shielding and antishielding effects) and of deviations from pure SL-coupling for the states5 D 1,2,3,4. |
