Mean Lifetime

Using the level-crossing technique the following relations between the hyperfine structure constant A and the gj value of the (5p6s)3P10-term were determined for both the stable isotopes Sn117 and Sn119:A117 = — 159,57(4) mK · gJ/1,380; A119 = — 167,01(4) mK · gJ/1,380.From the width of the level-crossing signal a mean lifetime τ = 4,5(7) · 10-9 sec was deduced.

G Factors

The EPR g factors and the hyperfine structure constant A factors for Cr3+ in MgS and SrS are theoretically studied by using the two-spin-orbit (S.O.)-coupling-coefficient formulas for a 3d3 ion in octahedra based on the cluster approach. In these formulas, both the contributions due to the S.O. coupling coefficient of the central 3d3 ion and that of ligands are taken into account. Based on these studies, the g and A factors of Cr3+ in both MgS and SrS are satisfactorily explained. The results are discussed.

Good Agreement

The isotropic g factor and hyperfine structure constant for Ir4+in CdO are theoretically studied from the perturbation formulas of these parameters for an octahedral 5d5cluster based on the cluster approach. The calculated results show good agreement with the experimental data. The ligand orbital contributions should be taken into account due to significant covalency of the system with high impurity valence state even in the oxide.
