Abstract

The g factors of the 2 + 1 states in 54 Fe and 58 Fe have been measured relative to the 2 + 1 state g factor of 56 Fe using the transient-field technique in inverse kinematics. The results are in satisfactory agreement with recent shell model calculations in the fp model space. For 56 Fe and 58 Fe the g factors approach Z/A and are therefore also consistent with collective interpretations of these 2 + states.

“…The experiments used the ANU Hyperfine Spectrometer [10]. Experimental procedures were similar to those described elsewhere [11][12][13][14][15][16][17].…”

“…No evidence for multiple excitation was observed in 56 Fe (see Ref. [18] for a representative γ -ray spectrum). Data were analyzed for the three particle detectors separately.…”

“…The rationale for this choice of transient-field parametrization, and further details of the calculational procedure, are given in Ref. [18].…”

“…Most of the precession data for 56 Fe were taken with the two 20% HPGe detectors (at ±115 • ) replaced by NaI detectors, as described in Ref. [18].…”
