Abstract

A new method is proposed for the derivation of mass spectrum cracking pattern which is supposed to be possessed by ions in a variety of electron bombardment type ion sources. The cracking pattern of Argon in grid type, axial type and Nier type ion source is obtaind. The pattern coefficient was derived from partial ionization cross section of the sample gas with aid of l-V distribution data of ionizing electron, which represents the specific ionizing electron path length li of an electron having an energy of eVi.
