Equilibrium Charge Fractions of Aluminum Ions in Nitrogen from 0.4 to 4.0 MeV

Abstract

Equilibrium charge fractions have been measured for aluminum ions at energies from 0.4 to 4.0 MeV passing through nitrogen gas. Charge states from 0 to ${7}^{+}$ were observed. The mean charge increased from 1.47 at 0.4 MeV to 3.84 at 4.0 MeV.
