Abstract
An electron-spin-resonance study of the dynamic Jahn-Teller effect in Ni1+ and Ni3+ in MgO at liquid-helium temperature is reported. For both ions the spectra arise from strain-split ground vibronic doublets, with a small admixture of an excited singlet. From the anisotropy of the linewidth it follows that the symmetry of this singlet is A2 for Ni1+ and A1 for Ni3+.
