摘要：
The axial and planar potential for x-particles in copper single crystal disordered by dumb-bell configuration (DBC) or body-centered interstitial (BCI) is calculated according to the continuum potential approximation by using Moliere potential and Biersack's universal potential and compared with the channeling potential of the normal lattice. The calculations showed that the axial potential for DBC or BCI are the same, but the planar potential has different estimations for each kind of lattice disorder. The point of minimum potential in the disordered lattice has been determined for both axial and planar channel.
