Nuclear g-factors and structure of the high-spin 10+, 12+ and 7− states in isotopes 196, 198Hg
The integral perturbed angular distribution (IPAD) method in an external magnetic field has been used to measure the g-factors of isomers in the 196,198Hg nuclei, populated in the (α, 2n)-reaction. The results are as follows: 196Hg, g(12+ and 10+ ) = -0.19(6), g(7- ) = -0.030(17); 198Hg, g(12+...

Summary: | The integral perturbed angular distribution (IPAD) method in an external magnetic field has been used to measure
the g-factors of isomers in the 196,198Hg nuclei, populated in the (α, 2n)-reaction. The results are as follows: 196Hg, g(12+
and 10+
) = -0.19(6), g(7-
) = -0.030(17); 198Hg, g(12+
and 10+
) = -0.18(8), g(7-
) = -0.033(14). The intrinsic structure of
the isomers is discussed. Measured g-factors of 12+
and 10+
states support model “axial-symmetric oblate rotor + twoquasiparticles”.
Measured g-factors of 7- states in mercury allows to confirm prediction of model “axial-symmetric rotor
plus two-quasiparticles” for Hg nuclei and transient form in the platinum nuclei. |
