Cross sections for ionization of water vapor by 7–4000-keV protons

Cross sections for ionization of water vapor by 7-4000-keV protons.

Total, partial, and electron-capture cross sections for ionization of water vapor by 20-150 keV protons.

We present experimental results for proton ionization of water molecules based on a novel event by event analysis of the different ions produced (and lost). We are able to obtain mass analyzed product ion signals (e.g., H2O+, OH+, O+, O++, H+) in coincidence with the projectile analyzed after the collision, i.e., either being H+, neutral H after single electron capture during the ionization eve...

Differential cross sections for secondary electron production by 1.5-keV electrons in water vapor.

Differential Cross Sections for Ionization of Water Vapor by High-Velocity Bare Ions and Electrons

A semiempirical model of single differential cross sections (SDCS) for ionization of water vapor by fast electrons and bare ions is presented. At low secondary-electron energy, the model is based on an asymptotic expansion of the first Born approximation with coefficients, that are independent of projectile properties, evaluated from experimental photoabsorption and protonimpact ionization data...
