We present ionization cross sections for antiproton and helium collisions based on ab-initio time-dependent coupled channel method. In our calculations a finite basis set of regular helium Coulomb wave packets and Slater function were used. The semiclassical approximation was applied with the time-dependent Coulomb potential to describe the antiproton electron interaction. Three different projectile energies were considered as 10, 50 and 100 keV. We found clear evidence for the formation of the…

QUANTUM MECHANICAL TREATMENT OF ION COLLISIONS WITH MANY-ELECTRON ATOMS

Based on the concepts of time-dependent density functional theory we present calculations for multiple electron processes in ion-atom collisions. The gist of this article is to reveal the di erent…

The Hyperfine Interaction

In this chapter we shall apply the formalism of effective operators, introduced in the previous chapter, to the hyperfine interaction. The idea of using effective operators to analyze experimental…
