Abstract
The H2 molecular vibrational distribution function that is formed in a flow of molecular hydrogen is calculated. It is assumed that the hydrogen stream flows in a planar channel and passes through two sections in succession. In the first section a cesium-hydrogen discharge and preliminary vibrational pumping of H2 molecules occur. In the second section, where there is no discharge, the v-v exchange process results in a considerable increase in the density of vibrationally excited molecules in a certain upper part of the vibrational spectrum. The possibility of using the vibrational distribution function produced in this manner to generate negative hydrogen ions as a result of subsequent dissociative attachment of electrons to vibrationally excited molecules is discussed.
