1a. To determine g factor for 111Cd in a ground state and tn the level 0f 245keV I used formula which relates the nuclear spin and the spin magnetic moment, which are present in the tables. g=2ump/I. For the ground state g=-2.38mp and for he 245keV level g=-0.613mp.
1b. To calculate g factor for free electron I used the formula for a particle with spin 1/2. g=ush/2piuBS.
1c. I have no idea how to calculate it.
If the formula is g=u/I than:
a) g factor for the ground state of 111Cd is -1.38 for 245keV is -0.31,
b) g factor for free electron which spin is 1/2 and um=1 is 2,
c) For free neutron of g=-3.826, and spin equal 1/2 its magnetic moment is -1.913
