The gyromagnetic ratios of the 4[, 6 3, and 2 7 states in ls6W were measured relative to that of the 2 7 level by means of the transient field implantation perturbed 7-ray angular distribution technique. The nuclei in the states of interest were Coulomb excited using a beam of 220-MeV 63Cu projectiles and recoiled swiftly through a thin, polarized Fe foil.The present measurements yielded ratios g(4[)/g(2~)=l.04_+0.07, g(6~-)/g(2~-)=1.03 _+0.20 and g(2~-)/g(2~-)=0.63_+0.13. The sizable disparity between the measured gfactors of the ground-and excited-band is examined within the context of the interacting boson approximation model.

The relative gyromagnetic ratios of the 2t states in 70,72,74, 76 Ge were measured simultaneously by means of the thin-foil, perturbed y-ray angular distribution technique utilising the transient hyperfine field manifest at nuclei of Ge ions rapidly traversing polarised Fe. The states of interest were Coulomb excited using 75-MeV 34S projectiles incident upon a natural elemental Ge target. The present results are compared with previously reported measurements and collective model expectations.
