Atomistic modeling of the channeling process with account for ionizing collisions: Preliminary results

We present preliminary results of simulations of the channeling process with account for the ionizing collisions that accompany the passage of a charged projectile in a crystalline medium. The simulations have been performed by means of the software package. taking into account that ionizing collisions are random, fast and local they can be incorporated into the classical molecular dynamics framework according to their probabilities. The description of this methodology is given in the paper. The case studies presented refer to channeling of 195, 270 \& 855 MeV electrons and of 270 \& 500 MeV positrons in single diamond crystals along the (111) (electrons) and (110) (positrons) planar directions.
