摘要: A Knudsen cell has been combined with a Fox ionization source to perform accurate measurements of the potentials monoatomic metal vapors and appearance their polyatomic ions. The relative probabilities silver by electron impact have studied near threshold, as was also influence temperature on structure efficiency curve. This study enabled us find narrow peaks superimposed ion yield correlated groups energy levels known spectroscopically. We explain different mechanisms which appear be operative in auto-ionization processes threshold. curve for formation Ag2+ studied.
