Magnetic moment components in the nuclei of the rare-earth elements

The A and B constants of the superfine splitting in the optical spectra of the 60143,145Nd, 63151,152,153,155Eu, 64155,157Gd, 71175,176Lu rare-earth elements are measured. The method of the resonance laser fluorescence in the atoms parallel beam was used thereby. The values of the 1Δ2 superfine magnetic anomaly are determined from the comparison of the ratios of the A magnetic dipole constants of the neighbouring (1) and (2) isotopes with the odd number of protons or neutrons for various atomic levels. The data on the change in the spin constant of the αs magnetic moment are obtained from the 1Δ2 value. The relationship of these parameters with the peculiarities of the atomic and nuclear structure of the studied elements
