Laser-Rf double-resonance studies of the hyperfine structure of metastable atomic states of55Mn
Abstract
The hyperfine structure (hfs) of the metastable atomic states 3d64s6 D 1/2, 3/2, 5/2, 7/2, 9/2 of55Mn was measured using the ABMR- LIRF method ( atomic beam magnetic resonance, detected by laser induced resonance fluorescence). The hfs constants A and B, corrected for second order hfs perturbations, could be derived from these measurements. The theoretical interpretation of these corrected A- and B-factors was performed in the intermediate coupling scheme taking into account the configurations 3 d 54 s 2, 3 d 64 s and 3 d 7. Examining the influence of the composition of the eigenvectors on the hfs parameters < {r^{ - 3} } rightrangle ^{k_s k_l } it was found, that for the configuration 3 d 64 s the two-body magnetic interaction should be considered in the calculation of the eigenvectors. Investigating second order electrostatic configuration interactions and relativistic effects and using calculated relativistic correction factors we obtained for the nuclear quadrupole moment of the nucleus55Mn a value of Q=0.33(1) barn, which is not perturbed by a shielding or antishielding Sternheimer factor. The following hfs constants have been obtained:
