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+...
