Abstract
The sorption of hydrogen by thin niobium films, evaporated at 10−9 torr, has been studied at low pressures and at temperatures of 77° and 293° K. The measurements have been carried out employing a Bayard-Alpert gauge and an omegatron type mass spectrometer, both supplied with lanthanum hexaboride coated filaments. For the very thin films considered (< 0.1 mg|cm2) the sorption capacity was found to be independent of the temperature and directly proportional to the evaporated niobium. The measured capacity was found to correspond to an atomic ratio H:Nb of about 1:2. The initial sorption rate seems to be independent of the film thickness. The shape of the curve relating sorption rate to quantity sorbed is different at the two different temperatures.
