Ion collisions in very strong electric fields
Luca Salasnich

and Fabio Sattin§
A classical trajectory Monte Carlo (CTMC) simulation has been made of charge exchange and ionization processes between a hydrogen atom and fully stripped ions embedded in very strong static electric fields (of order of 
), which are thought to exist in cosmic and laser-produced plasmas. Calculations show that the presence of the field affects absolute values of the cross sections, enhancing ionization and reducing charge exchange. Moreover, the overall effect depends upon the relative orientation between the field and the nuclear motion. Other features of a null-field situation, such as scaling laws, are revisited.
