Abstract

On-line β-NMR measurements on nuclei oriented at low temperatures of the magnetic dipole moment of ${}^{71}{Cu}$ ( $N = 42$ ) are reported, with the result $μ$ ( ${}^{71}{Cu}$ ) $= + 2.28 (1)$ nuclear magneton (n.m.). The value shows a significant difference from $μ$ ( ${}^{67}{Cu}$ ) $= + 2.54 (2)$ n.m., revealing asymmetry with respect to $N = 40$ . This effect presents a challenge to theoretical interpretation.
