36. (a) The potential energy of the atom in association with the presence of an external magnetic field GBextis given by Eqs. 32-31 and 32-32: orbextorb,extext.zBUBBmBµµµ=−⋅AGFor level E1there is no change in energy as a result of the introduction of GBext, so U ∝mA= 0, meaning that mA= 0 for this level. (b) For level E2the single level splits into a triplet (i.e., three separate ones) in the presence of GBext, meaning that there are three different values of
