The perturbed angular correlation transient field technique is used to measure the precession of nuclear magnetic moments of low lying excited states in isotopes of silver, neodymium, samarium, and gadolinium. The precession measurements are used to explore three main areas of study. First, from the measurements made on /sup 150/Sm transversing gadolinium targets, the temperature dependence of the transient hyperfine field is deduced at /sup 150/Sm nuclei traveling at 2 < v/v/sub 0/ < 4. These are compared with similar measurements made using iron targets. Second, the deduced values of the g-factors of the 2/sub 1/ + states in even neodymium, samarium and gadolinium isotopes are discussed in connection with a possible proton shell closure at Z = 64. Third, the deduced values of the g-factors of the 3/2/sub 1/- and 5/2/sub 1/- states of /sup 107,109/Ag are compared to various theoretical predictions in order to explore any simple relationships that may exist between these states and the first 2/sub 1/+ states of neighboring even-even nuclei.
