The Nature of the Effect of Precession-Frequency Mismatch between 129Xe and 131Xe Nuclei under Spin-Exchange Pumping by Alkali-Metal Atoms

Resumo

The effect of precession-frequency mismatch between ¹²⁹Xe and ¹³¹Xe xenon-isotope nuclei, which arises under spin-exchange pumping by optically oriented alkali-metal (Cs) atoms and affects the characteristics of measuring and navigation devices based on balanced Schemes with spin-exchange pumping of xenon isotopes, has been investigated. An attempt to explain this effect has been made, and methods for its minimization and elimination have been proposed and experimentally verified.
