Abstract

The characteristic third body gas pressure P₀ - the third body gas pressure for which the molecular breakup rate τ^-1 is equal to the spin-rotational frequency γ N h {combining short stroke overlay} - has been measured for N₂ and He in ¹³³Cs¹²⁹Xe systems. Nitrogen, as a third body gas in the formation or breakup of CsXe van der Waals molecules, is found to be 2.2 times as effective as helium. The relaxation rate of ¹²⁹Xe nuclear spin in ¹³³Cs as function of dimensionless third body gas pressure ( P P₀) is described by a universal spin relaxation function.
