“…While only the overall transition intensity was adjusted to fit the data for the 548-keV E2 transition, the mixing ratios were also varied to fit the correlations for the mixed were also in agreement with those measured and are similar to those published for la4W in [13]. A partial level scheme of 197Au which incorporates several firm spin assignments determined in our related study [20,21] is shown in Fig. 5.…”

“…In earlier publications [5,6,8] we discussed the abrupt discontinuity in TF strength which occurs between 76Os and 7sPt ions traversing polarized Fe hosts with velocities ~ 0.02 c. In contrast with TF studies using Fe hosts, no discontinuities [20,21]. Shown at the left of each level are the relative direct population intensities (with that to the 5/2~-taken as 100) derived from the measured particle-7 correlation data of Run II.…”

Transient field precessions were measured for levels in the nuclides of 182'184'186W and 197Au as their ions simultaneously traversed polarized Fe and Gd hosts. Consistent sets of gyromagnetic ratios were inferred for the lowest 5/2 + and 7/2 + states in 197Au using these two ferromagnetic host media, provided that (i)the transient field for Au ions in Gd is calibrated using the W in Gd precessions (simultaneously measured) and,

The transient-field technique has been used to measure, with considerably improved precision, the g factors of the 3/2 + and 5/2 + states in 125 Te at 444 and 463 keV, respectively, relative to the g factor of the first excited state in 126 Te. Together with shell model and weak-coupling core-excitation model calculations, the g-factor measurements provide insight into the orbital occupation of the odd neutron for the low-excitation states in 125 Te. A new 9/2 + level at 1029 keV, together with a firm 7/2 + spin assignment for the level at 1018 keV, identifies candidate states for the coupling of the s 1/2 neutron to the 4 + core excitation.

The design and operation of apparatus for measurements of in-beam hyperfine interactions and nuclear excited-state g factors is described. This apparatus enables a magnetic field of about 0.1 tesla to be applied to the target and the target temperature to be set between ∼ 4 K and room temperature. Design concepts are developed mainly in terms of transient-field g-factor measurements following Coulomb excitation by the implantation perturbed angular correlation (IMPAC) technique. The formalism for perturbed angular correlations is outlined and a figure of merit for optimizing these measurements is derived to inform design. Particle detection is based on the use of silicon photodiodes of rectangular shape. The particle-γ angular correlation formalism for this case is described. The experimental program to date includes temperature-dependent studies of hyperfine fields, transient-field g-factor measurements, and time-dependent perturbed angular distribution (TDPAD) studies.
