Chapter 17
Semi-classical Theory of Radiations
17.1 INTRODUCTION
In Chapter 16, we discussed the time-dependent perturbation theory and studied the time-development of states of (one-particle) system. In particular we studied the time-dependence of states in cases when perturbation is switched on adiabatically or suddenly In this chapter, we shall study time dependence of states of (one-electron) atom or ion under the time-dependent harmonic potential.
In particular we shall study the effect of electromagnetic field on the states of (one electron) atom or ion. We shall study the transition probability of atoms from one state to the other. Thus we shall study the phenomenon of stimulated emission and absorption. In this study, the electromagnetic ...
