In this study, the g-factors of low-lying excited states in {sup 103}Rh, {sup 111,113}Cd and {sup 123,125}Te have been measured using the Perturbed Angular Correlation and Transient Field Technique (PACTRAF). In this technique, an excited nucleus is recoiled through a thin polarized ferromagnet where it is subject to a transient hyperfine field and then brought to rest in a field-free material. The g-factor is proportional to the precession of the nuclear spin in the transient field. In the case of Rh and Te isotopes, the field is determined from a parameterization determined at Rutgers from measurements on nuclei across the periodic table, whereas the Cd isotopes are calibrated with respect to {sup 110}Cd whose g-factor is known from direct measurements. From the observation of gamma ray angular distributions, several multipolarity mixing ratios, {delta} (E2/M1), have been determined. It was found that theoretical single particle shell model values are inconsistent with the measurements. The weak coupling core-excitation model yields, overall, better predictions of the magnetic moments measured. Further, some success was achieved with the Nilsson model in the Cd and Te isotopes.
