We present in this work an alternative set of basis functions, named Quasi Sturmian Functions, useful to describe two- and three-body scattering processes.These basis functions have analytical closed form for the case of a Coulomb potential. As a consequence it is possible to give analytical expressions for matrix elements when solving two- and three-body scattering problems.
