g factor of the 2{sub 1}{sup +} state of {sup 170}Hf

The g factor of the 2{sub 1}{sup +} state of {sup 170}Hf was measured by perturbed {gamma}-{gamma} angular correlation in a static external magnetic field. The result, g(2{sub 1}{sup +})=0.28(5), extends the systematics of g factors of even-even Hf isotopes to N=98 and enables a better test of theor...

Description
Summary:The g factor of the 2{sub 1}{sup +} state of {sup 170}Hf was measured by perturbed {gamma}-{gamma} angular correlation in a static external magnetic field. The result, g(2{sub 1}{sup +})=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{sub 1}{sup +}) 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.
