Transient field g-factor measurements on the 21+ states of 32S and 34S

Abstract

Transient field integral precession measurements have been performed on the first-excited Jπ = 2+ states of 32S and 34S with the IMPAC technique on recoil into magnetized iron single-crystal frames. The results were analysed with an empirical parametrization of the field. This yields g-factors of g = +0.47 ± 0.09 and +0.50 ± 0.08 for 32S and 34S, respectively. In the present cases the influence of static magnetic hyperfine fields is negligible due to the short mean lives for 32S and 34S of 0.23 and 0.46 ps, respectively. Various complex model calculations yield g-factors in good agreement with experiment. Measured g-factors, including the present data, for light self-conjugate and neutron-excess Tz = 1 nuclei are also briefly discussed. The measured value of the g-factors for 32S confirms the empirical description of the transient field.
