RESEARCH INVESTIGATION DIRECTED TOWARD EXTENDING THE USEFUL RANGE OF THE ELECTROMAGNETIC SPECTRUM.
Abstract
Successful observations have been made on the spectra of 6328A light scattered from carbon dioxide near the critical temperature and critical density. A technique has been developed for measuring the two relaxation times characterizing the disorientation of optical aligned atoms in a vapor. The method consists of alternately existing pure dipole for pure quadrupole components of the density matrix which give rise to m=1 zerofield level-crossing signals. A discriminator against m=2 signals simplifies analysis of the data. Measurements of these relaxation times will give considerable information on the coupling of an excited atom to its statistical environment. (Author)
