In this section we apply our results to the concrete special measurement model of quantum stochastic mechanics -- the only dynamic model which is considered in the theory of continuous in time indirect measurements. This measurement model satisfies the principles of nondemolition observation [9-15]. ...

... En = -R/n2, with E0 = ħ2/2ma02 = 13.6 eV The example we gave in Lecture 13 corresponds to n=2, l=1, m=0. The energy level diagram starts at -13.6 eV, which is the binding energy of the ground state n = 1, and continues with -3.4 eV, which is the binding energy of the first excited state, and so on. ...
