โœฆ Synopsis

Although the VUV continua emitted by rare gas excimers have been extensively investigated, no theoretical calculations are available for their intensity distribution. In this Letter a semiclassical method, based on the split operator technique, has been used to describe the collisions between Ar2 ( 3 Zz ) excimers and ground state Ar atoms. The experimentally observed intensity distribution in the so-called first and second WV continuum has been qualitatively reproduced. The calculations yield a value of u = (4.10 + 0.27 ) x 10"~ (s-' ) for the global vibrational relaxation process frequency, where p is the pressure in Torr.

We calculate semiclassical S-matrix elements Stun by numerical integration along complex-valued trajectories, by avoiding (simply) previously reported trajectory divergences. Now, one can numerically calculate even I Smnl ~ 10 -11 for the Secrest-Johnson system (their lowest I Smn 12), instead of on

The vibrational energy exchange between the stretching modes of Hz0 in the H20+Ar collision has been studied in a semiclassical method in the temperature range of 200-3000 K. The energy exchange probability increases slowly, but nearly linearly, with temperature over the entire range, reflecting a n
