Spontaneous Radiation of a Molecule Inside a esonator
resonator. The aim of this article is to derive a general
formula for the radiation probability of a molecule in a
resonator. It is assumed that the energy spectruin of i-)
molecule inside the resonator consists of two non-overlappiiig
continuous bands having an identical width 6E and
average levels EI and E 2 - The ensemble of the con-
tinuous quantui-ii numbers determining a state will be
denoted by a ; the energy in the state a is equal to
Ea . The problein consists of determining the probability
W0 of a spontaneous transition (per unit time) of the
molecule from a state a 2 corresponding to the second
energy band into a state a 1 in the first energy band.
