Abstract

The hyperfine structure (hfs) of the

3 d^{8} 4 s^{2} {}^{3}F_{2}

metastable atomic state of

{}^{61}{Ni}

has been measured by the atomic-beam magnetic-resonance technique. Isotopic enrichment of the normally 1% abundant

{}^{61}{Ni}

was necessary to achieve adequate intensity. The results, when combined with earlier hfs measurements of the

{}^{3}F_{4, 3}

states of

{}^{61}{Ni}

, allow a comparison with predictions of Bauche-Arnoult's recent theoretical treatment of the effects of configuration interaction on hfs. Good agreement is found. Similar experimental results for the Hund-rule terms of other

3 d^{N} 4 s^{2}

atoms are tabulated. The electron spin density at the nucleus, as determined from the experimental hfs results, is compared with recent unrestricted-Hartree-Fock calculations.
