g factor of the 2(1)(+) state of (170)Hf

Abstract

The g factor of the 2(1)(+) state of (170)Hf was measured by perturbed gamma-gamma angular correlation in a static external magnetic field. The result, g(2(1)(+))=0.28(5), extends the systematics of g factors of even-even Hf isotopes to N = 98 and enables a better test of theoretical models. The g(2(1)(+)) experimental values of these isotopes exhibit a remarkable constancy as a function of neutron number. This phenomenon, which was also observed for other isotopic chains in the Gd-W range, is explained in terms of a recently proposed empirical model.
