Now we have to go back to the beginning and do the problem all over again. Much of the work is, however, done—we need only to add the effects of the new terms. Let's take a constant magnetic field in the -direction. Then we have to add to our Hamiltonian operator the two new pieces—which we can call : Using Table 12-1, we get right away that How very convenient! The operating on each state just gives a number times that state. The matrix has, therefore, only diagonal elements—we can just add the coefficients in (12.28) to the corresponding diagonal terms of (12.13), and the Hamiltonian equations of (12.14) become
