DETERMINATION OF THE SPIN COUPLING CONSTANTS IN THE ⁸⁷Rb ¹²⁹Xe VAN der WAALS MOLECULE

The measurement of the ratio of the repolarization signal to the optical pumping signal of the Rb atoms has been used to determine the ratio  of the spin rotation coupling constant to the spin exchange coupling constant of the ⁸⁷Rb ¹²⁹Xe Van der Waals molecule. The value  = 3.4±0.1 is inferred from these studies. The author has also given the magnitudes of the spin rotation and spin exchange interactions.
