Transient field measurements of g-factors for 28Si and 30Si

“…10 of ref. 4)]. Since the optimum recoil energies for 288i and 3°Si are 1.0 MeV and 0.5 MeV, respectively, the yield measurements were limited to bombarding energies ranging a few MeV above the Coulomb Fig.…”

Anomalously large transient field through polarized electron capture

“…This is explained quantitatively by capture of polarized Fe electrons into 2s vacancies in the moving ion.Transient magnetic fields have been used for the determination of g-factors of short-lived excited states of nuclei recoiling into ferromagnets [1][2][3]. In these measurements the magnitude of the transient field was estimated by adjusting the Lindhard and Wmther (LW) theory [4], which treats the scattering of (polarized) electrons by an ion on slowing-down in a polarized ferromagnet.…”

“…The first-excited 2 + state of 28Si is well suited for an integral precession measurement, since its mean life r m = 0.68 pS is comparable to the slowing-down time in Fe, such that static field effects are negligible. The experimental set-up is described in detail in earlier papers [2,3] ; the latter also reports the 28Si measurement at the intermediate recoil energy. Each experimental point, including the measurement of beam-bending corrections [2] required one week of accelerator time.…”

“…The experimental set-up is described in detail in earlier papers [2,3] ; the latter also reports the 28Si measurement at the intermediate recoil energy. Each experimental point, including the measurement of beam-bending corrections [2] required one week of accelerator time. The measurements clearly show a precession increasing with recoil energy (table 1).…”
