This was achieved by the combination of the boundary conditions and scattering potentials and the combination of non-overlapping scattering potentials within the context of the scattering theory to obtain the transition matrix, which is the most important parameter in scattering problems due to its direct relation with the scattering cross section.]]>Adam, L.,1998Eugen, M.,2003Fayyazuddin and Riazuddin,1990Hong-Jun, Y.,1999Leonard, I.S.,1995Ni, G. and S.
