Abstract
Frequency crossing experiments using thermal phonons carried out on V-doped Al2O3 show that the 280 MHz hyperfine splitting of V3+ can easily be resolved by this technique at a phonon frequency of 166 GHz. From the values of the linewidths of the hyperfine lines it is clear that the effect of T2 symmetry strains is very much less than that of E-type strains. This suggests that the effect of T2 strains is quenched by a dynamic Jahn-Teller effect with gamma <- mod and mod G15 mod are very similar to mod G44 mod and mod G51 mod and not larger as previously found.Keywords
