Tw. Francisco et al., ROTATIONALLY INELASTIC-SCATTERING OF C2H2 FROM LIF(100) - TRANSLATIONAL ENERGY-DEPENDENCE, Physical review letters, 77(7), 1996, pp. 1402-1405
We report the first results from a new experimental apparatus designed
for the general investigation of energy transfer in molecule-surface
scattering. The translational energy dependence of the rotational temp
erature of C2H2 scattered from LiF(100) has been measured, yielding re
sults which are different from any data of this type previously report
ed. Our preliminary interpretation of the results is in terms of vibra
tional excitation with increasing incident translational energy.
