β¦ Synopsis
The principal route for decay of Hg 6s6~(~P,) in xenon is shown to be bimolecular deactivation to the mercury ground state, with rate coefficient 9.1 x lo-l3 cm3 molecule-' s-l. , relaxation to the 3Po state plays a negligible role. The equilibrium constant of the reaction Hg(3P,) + Xe # HgXe(A 30'), has been recorded as 1.73 x 10v20 cm3 molecule-' at 293 K.

The rate coefficient of the process Hg 6s6p( 'P 0-+3P, ) induced by nitrogen collisions has been measured over the range 285 to 340 K. The temperature variation closely matches that of the concentration of Nz( u= 1). The results support the electronic to vibrational energy-transfer mechanism for the
First proposal is made to measure the ratio of stimulated photon echo power corresponding to two different mutual orientations of exciting pulses polarizations as a function of the buffer gas pressure to extract the spectroscopic information concerning the relaxation rates difference of orientation
Pressure effects on the decay rates of the Xe 6p [ l/2] ,\_, (O-800 mbar) and 6p [ 3/2] z (O-200 mbar) levels have been measured up to 6 x 10' s-' using two-photon excitation. An analysis in terms ofbinary and ternary total quench rates for both transitions is presented. A radiative lifetime of 28.2
