Population Inversion and Continuous Optical Maser Oscillation in a Gas Discharge Containing a He-Ne Mixture

Abstract

cos'8 sin'8. However, for Fe'+ ions in MgO the cubic field causes a small admixing of states' and consequently, a slight deviation of the transi- tion probability from a simple cos'8 sin'6t de- pendence. Therefore, exact wave functions have been used in computing the theoretical angular variation.
