Abstract

Using the technique of nuclear magnetic resonance on oriented nuclei, the magnetic hyperfine splitting frequencies

ν_{M} = \frac{g μ_{N} B_{HF}}{h}

of the 11/

2^{-}

state in

{}^{195}{Au}

(

T_{\frac{1}{2}} = 31

sec;

E = 319

keV) in Fe and Ni have been determined as

ν_{M} ({}^{195}{Au}^{m} F e) = 979.8 (4)

MHz and

ν_{M} ({}^{195}{Au}^{m} N i) = 226.3 (2)

MHz. Taking the known hyperfine fields of

{}^{197, 198}{Au}

in Fe and Ni and correcting for hyperfine anomalies a value of

| g | = 1.123 (17)

is derived for the nuclear

g

factor of

{}^{195}{Au}^{m}

.
