Analytic solutions of the Schrodinger; equation are presented for a repulsi
ve 1/r(3) potential. They lead to an in-depth understanding of scattering b
y a purl repulsive 1/r(3) interaction including exact cross sections and ph
ase shifts. Scattering by any potential which is asymptotically a repulsive
1/r(3) is also discussed. [S1050-2947(99)03704-X].
