Abstract
The paper is devoted to the study of two types of coherent transient processes, viz., coherent radiation in time-separated fields (CRSF) and photon echo (PE) in a traveling wave in SF6 gas. Study of CRSF signals produced at instants of time t = T + nT (T is the delay time between the exciting pulses and n is an integer) has made it possible to measure the relaxation rates of the polarization and of the populations in SF6 gas and draw qualitative conclusions concerning the character of the collisions. Damping of PE signals as a function of the delay time is nonlinear in the region of short T and permits measurement of the rates of rotationally inelastic processes, as well as of the contribution of other collisions with small velocity change.
