Abstract: | The particle motion equation has been reduced to the pendulum equation with a δ moment by using sine squared potential. The phase planar characteristics have been analysed for a non perturbed systeam . The dechanneling effects have been calculated numerically for a perturbed system. The relationship between the dechanneling fraction and superlattice deformation in resonance has been discussed. |
