The scattering solutions are obtained in terms of hypergeometric functions and the condition for the existence of transmission resonances is derived. It is shown how the zero-reflection condition depends on the shape of the potential.10 pages, Revtex. To appear in Phys. Rev. AHigh Energy Physics - TheoryMathematical Physicstext
