Paper Abstract

Long-lived quantum states in gases are analyzed from the view point of their nature, their formation under action of laser radiation, their detection and decay. The long lifetime of molecular vibro-rotational levels was detected by photon echo technique for slowly moving particles. Polarization moments of degenerated molecular states, created by resonant polarized radiation of CO2 laser, were investigated by using stimulated photon echo technique. Long lifetime of polarization moments was detected in experiments on collisional decay in a gas SF6 and its mixtures with He and Xe. Non-elastic depolarizing collisions contribute within experimental errors. Long-lived stats applications in high resolution spectroscopy and spectral references design are analyzed.
