Multiple Self-Pumped Phase-Conjugated Waves by Pulsed Laser

Abstract

ESR spectra of whole ret tissues have been compared at low and room temperatures, end the effects of temperature variation on line widths and saturation measured. It is concluded that the two major fectors accounting for the differences in spectra above and below freezing are line broadening with temperature and chenge of spin state through 2 7 3 '~. It is also concluded from the saturation studies that no free radical artefacts ere produced by the freezing method.
