摘要: The hyperfine interaction of194Ir (j π =1−;T1/2=19.4 h) in Fe and Ni has been investigated with the technique of nuclear magnetic resonance on oriented nuclei. For both systems electronic-orbital-momentum induced electric quadrupole splitting could be resolved. frequencies,v M =¦gμ N BHF/h¦ andv Q =e2qQ/h, respectively, were measured as:194IrFe:v m =408.54 (23) MHz;v q =−2.47(20) MHz;194IrNi:v =135.24(5) =−1.23 (3) MHz. Taking into account a 3% uncertainty arising from anomalies theg-factor is deduced as ¦g¦=0.39 (1). moment,Q=+0.352 (18)b, slightly smaller than expected known systematics deformation parameters this mass region.
