| Summary: | A single centered expansion with a finite Hilbert basis set and double ionization cross sections of He are calculated but fall below experiment above 300 keV. Results of p+ + He cross sections calculated via the independent event and cross sections for protons are in poor agreement with excellent agreement with experiment from 10 keV to 300 keV experiment. for He+ and He by antiproton and proton projectiles. Single good agreement with experiment above 40 keV but differ below has been used to calculate the electron removal probabilities independent event model being slightly preferred below this independent particle models for antiproton projectiles are in measurements are unavailable. For He single ionization, MeV for protons. Results for p- + He+ are in good agreement model from 10 keV to 1 MeV for antiprotons and 25 keV to 1 single ionization cross sections are in excellent agreement this value. Double ionization results for p- + He are in time-dependent Schrodinger equation but experimental under the independent event and the independent particle value. And in contrast to antiprotons, double ionization with experiment for both models above 50 keV, with the with recent calculations based on a numerical solution to the |
