Description

The g factors of the 12+, 11-, and 8- isomeric states in 188Pb were measured using the time-differential perturbed angular distribution method as g(12+)=-0.179(6), g(11-)=+1.03(3), and g(8-)=-0.037(7). The g factor of the 12+ state follows the observed slight down-sloping evolution of the g factors of the i13/22 neutron spherical states with decreasing N. The g factors of the 11- and 8- isomers proposed as oblate and prolate deformed states, respectively, were interpreted within the rotational model, using calculated and empirical g factor values for the involved single-particle orbitals.
