Abstract

Measurements of rate coefficients for intramultiplet state transfer of Zn(4  3 P 1 →4  3 P J ’ ) by collisions with the rare gases are presented. The state&hyphen;to&hyphen;state binary rate coefficients are derived from least&hyphen;squares fittings of the time&hyphen;resolved triexponential behavior of the 4  3 P 1 fluorescence. These rate coefficients were studied systematically over a temperature range of 690–1100 K in order to characterize the velocity dependence of the collisional coupling. The systematic behavior of the rate coefficients with varying temperature and noble gas species is qualitatively consistent with a nearly adiabatic coupling limit for noncrossing levels.
