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.

✦ Synopsis
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 deactivation of 'Pi to "PO by nitrogen.

The quenching cross-sections for collision of Hg( 6 'PI ) with HZ or D2 are measured in the temperature range 300 < T< 700 K. They show a minimum at Tz400 K, suggesting the occurrence of two processes, which may be interpreted using calculated HgH, potential energy curves. These processes depend on
