Abstract

The hyperfine structure of the (3(d 4s)1 D 2metastable state of43Ca has been measured using theABMR-LIRF method (atomic beam magnetic resonance, detected by laser induced resonance fluorescence). The measurements yielded for the magnetic dipole and electric quadrupole constantsA=−17.650(2) MHz andB=−4.642(12) MHz, respectively. From the measuredB factor the spectroscopic electric quadrupole moment (uncorrected for shielding effects) has been calculated to beQ(43Ca)=−0.062(12) barn. In addition, isotope shifts in the lines (3d 4s)1 D 2(3d 4p)1 F 03 and (3d 4s)1 D 2(4s 5p)1 p 01 for the stable calcium isotopes have been obtained by high resolution laser spectroscopy.
