Abstract
Abstract The quantum mechanical formalism for anomalous transmission of particles through perfect crystals using Debye model for lattice vibrations as described in an earlier work is applied to the case of Born-Mayer potential as the interaction between the incident particles and the lattice atoms. The results have been compared with those obtained by using the screened Coulomb potential in the earlier work. The dependence of the process on the incident particle energy and the temperature of the crystal has been established and is found to be similar to that obtained earlier. The channeling parameter (1 - e) has been found to depend upon the charge number z 1 of the incident particle (decreases with increasing z 1) in contrast to the results obtained with the screened Coulomb potential where (1 - e) depends only upon the screening properties of the electrons in the crystal.
