Excitation-ionization of helium in high energy collisions

We review recent developments in the process where excitation occurs together with ionization in collisions of helium with charged particles and photons. Various aspects of this process are discussed. The interrelation between cross section ratios for charged particle and photon impact is considered...

Description
Summary:We review recent developments in the process where excitation occurs together with ionization in collisions of helium with charged particles and photons. Various aspects of this process are discussed. The interrelation between cross section ratios for charged particle and photon impact is considered in the limit of first order perturbation.
