SOLUTION OF THE KINETIC-EQUATION FOR THE DEPOSITED ENERGY-DISTRIBUTION IN THE POWER CROSS-SECTION MODEL

A regular method for finding solutions of the equation for the distrib ution of energy deposited by atomic particles in elastic collisions is developed, using the model of an infinite random medium and power cro ss section. It is shown that in neglecting threshold energy the distri bution derivative has a singularity at the target surface. The calcula ted distributions and other functions connected with the problem are g iven for the case of equal masses of the projectile and target atoms.
