Nonlinear resonances of accelerated atoms and molecules
Abstract
An exact kinetic equation for the density matrix is obtained, which is valid for any interaction of a particle with an external field. This equation is used as a basis for studying the characteristics of the broadening of various nonlinear resonances under conditions where excited particles move with constant acceleration for the distance of one free path. It is shown that resonances of different origins act differently on the accelerated motion of a radiator. Under certain conditions acceleration can lead to splitting of nonlinear spectral structures or to their contraction.
