An expression is derived for the radiometer force which is valid at pressures from t'he free-molecule to the hydrodynamic region. A method is presented for obtaining inelastic collision cross sections (rotational relaxation times] from the detailed shape of the radiometer force curve. Some radiomete

โฆ Synopsis
Vrbrationally inelastic collision aoss sections are calculated for the He + Is system. The calculations -zse the exponential distorted wave method for thevibrationaI, and the infiite order sudden approximation for the rotational motions. Com-par&m OF our results with more exact calculations demonstrates the accuracy of the method.
