Anomalous fast recombination in hydrogen plasmas involving rovibrational excitation

Langmuir-probe measurements in a hydrogen-containing plasma jet show anomalous fast recombination that cannot be attributed to atomic processes such as radiative or three-particle recombination. In this paper a molecular mechanism, based on the charge transfer between the atomic hydrogen ions and th...

Description
Summary:Langmuir-probe measurements in a hydrogen-containing plasma jet show anomalous fast recombination that cannot be attributed to atomic processes such as radiative or three-particle recombination. In this paper a molecular mechanism, based on the charge transfer between the atomic hydrogen ions and the rovibrationally excited hydrogen molecules (H[sub 2][sup [nu],][ital J]+H[sup +][r arrow]H[sub 2][sup +]+H), is presented that explains the observed fast recombination.
