Abstract

Thermal transpiration measurements for helium, hydrogen, oxygen, nitrogen, carbon monoxide, and methane, are presented at characteristic temperatures of 163.6[degrees]K, 184.1[degrees]K, and 224.0[degrees]K. The "dusty gas" model proposed by Mason, Evans, and Watson describes well the variation of the ther- momolecular pressure difference as a function of the absolute pressure. The thermal transpiration data are used to compute the translational contribution to the thermal conductivity (translational Eucken factor) and the rotational collision number. [...]
