Abstract
The so-called anticlassical approximation for solutions of the radial Schrodinger equation with rapidly varying potentials U(r) for which \( kU)(-1)dU/dr\ much greater than 1 is worked out. With the diffuseness as a small parameter and using the method of matched asymptotic expans ions the regular and irregular wave functions for the Woods-Saxon pote ntial well with Coulomb and centrifugal barrier are obtained. The pene tration factor and the reduced width are also deduced and used to expr ess the resonance width.
