Abstract
The analytical behaviour of the scattering amplitude with respect to energy and angular momentum is considered for a group of soluble velocity-dependent potentials plus Yukawa potential. The Yukawa potential is brought in by means of a modified Born approximation. Convergent and semiconvergent expansions of the Jost functions are given for small and large energies.
