In the tabulation: magnetic moment is -0.5949 nuclear magnetons. g-factor can be found by dividing by the nuclear spin. Hence for 111-Cd in g.s. : -1.898.
The excited 245keV state has spin 5/2 and moment -0.766. Hence g-factor is -1.915
1b;
A Bohr magneton is -1836 times a nuclear magneton. Taking into account its 1/2 spin gives us a g-factor of -3672.
1c;
Its magnetic moment is the g-factor times spin: 1.913 nm (nuclear magnetons)
