Intermediate-velocity atomic collisions. VI: Screening, antiscreening, and related processes in He+ + (H2,He)

The total electron loss, target ionization, and simultaneous projectile-target ionization are measured for He[sup +] projectiles on H[sub 2] and He in the energy range of 1.5--4.0 MeV. The experimental data are in good agreement with calculations based on the independent-particle model including scr...

Zusammenfassung:	The total electron loss, target ionization, and simultaneous projectile-target ionization are measured for He[sup +] projectiles on H[sub 2] and He in the energy range of 1.5--4.0 MeV. The experimental data are in good agreement with calculations based on the independent-particle model including screening, antiscreening, and target-ionization probabilities as well as second-order mechanisms for the simultaneous projectile-target ionization.
