Abstract
A theoretical description of the positive column is presented which balances metastable loss rates due to radial diffusion and water vapor quenching with production by electron bombardment excitation. The predicted relative dependence of metastable atom density on discharge current and pressure similarity parameters is in agreement with present experiments and a previous more detailed theory.This publication has 7 references indexed in Scilit:
