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.
