Investigations of Townsend Discharges in Neon by Mass Spectrometry

摘要

The decay frequency of Ne( exp 3 P sub 2 ) atoms has been determined at 77 K and 295 K as a function of gas density from time sampling analysis of a N sub 2+ -ion impurity in the afterglow of a Townsend discharge in neon. From the sampling spectra of ions in the afterglow of a Townsend discharge, mobilities of positive ions in neon have been determined as a function of the reduced electric field strength at 77 K and 295 K. From mobility data the interaction potential as a function of intermolecular distance between a N sub 2+ ion and a neon atom is evaluated. (Atomindex citation 11:532626)
