| Abstract: | Model trajectory calculations of the energy transfer processes in collisions of Ar with highly vibrationally excited CH4, CD4, SiH4 and CF4 are performed. Special attention is payed to the calculation of the energy transferred to active (vibrational) degrees of freedom. The results support the diffusion model of excitation-dissociation and give the low pressure collision efficiency βc which qualitatively agrees with experiment in magnitude and temperature dependence. |
