We give an explicit analytic expression for the $S$-matrix in the case of an arbitrary central interaction inside a sphere of finite radius with a Yukawa-potential tail at large distances. The method uses the completeness of the wave functions outside the finite sphere and also the unitarity and the symmetry conditions for the $S$-matrix.
Mots-clés : $S$-matrix
Keywords: centrally symmetric potential, Yukawa potential.
