g-Factor of the 810.5 keV level in 58Fe

Defect phenomena in superconducting oxides and analogous ceramic oxides

“…In an NMR experiment, however, where a jump rate is obtained, it can happen that long-range diffusion is not involved, and that the characteristic time observed is merely some local motion. Thus in the perturbed angular correlation studies of Indium at (probably) Cu(1) sites in YBCO, in which the very low activation energy ((14+4) meV) is attributed to oxygen motion (Singh et al 1989b), one assumes this is a local activated process, as the energy is far smaller than from other experiments.…”

“…For 58 Fe, aside from the transient-field measurement of Brennan et al [5], there has also been a radioactivity measurement by the integral perturbed angular correlation (IPAC) technique [6]. When the result of that work [6] is corrected to account for more recent lifetime data [20] it becomes g(2 + 1 ) = 0.514(118).…”

“…When the result of that work [6] is corrected to account for more recent lifetime data [20] it becomes g(2 + 1 ) = 0.514(118). This value is in agreement with the present result.…”

“…Although stable, 58 Fe has an abundance of only 0.28%, and is not readily produced as a sufficiently intense beam from a natural iron sample by the ion sources in typical tandem laboratories. The previously reported g factors, measured by the transient field in conventional kinematics [5], and by integral perturbed angular correlations in radioactivity [6], have uncertainties of the order of 30%.…”
