Le Roy, R J

TDELAY solves the radial or one-dimensional Schroedinger equation for any given (smooth) potential in the continuum of energies above its ''dissociation threshold'' to determine the scattering phase shift and collisional time delay associated with any given energy and partial wave (angular momentum state). If desired, TDELAY will also automatically locate and determine the width of orbiting, or shape, resonances defined by local maxima of the collisional time delay as a function of energy.IBM370,303x;CDC7600,CYBER175; FORTRAN IV; OS/370 (IBM370), SCOPE 2.1 (CDC7600), NOS 1.3 (CDC CYBER175); 190K bytes of memory are required to execute the IBM370 version of TDELAY; the CDC7600 version requires 60,000 (octal) words.
