摘要：

We examine the convergence of average energy transfer with maximum impact parameter in classical trajectory studies of CS2 collisional relaxation by He, Xe, H-2, CO, CS2, and CH4, SF6 relaxation by He, Ar, Xe, and SF6, and SiF4 relaxation by Ar. This leads to estimates of the gas kinetic collision rate coefficient that are substantially larger (by a factor of 3.1 on average, and a maximum of 4.7) than are obtained using the traditional Lennard-Jones collision frequency.
