Authors: A. El-Hajj, H. Kobeissi, M. Korek
Program title: SSM
Catalogue identifier: ACJS_v1_0
Distribution format: gz
Journal reference: Comput. Phys. Commun. 74(1993)297
Programming language: Fortran.
Computer: IBM PC.
Operating system: MS-DOS.
Word size: 64
Peripherals: disc.
Keywords: Molecular, Structure, General purpose, Differential equations, Eigenvalue equation, Eigenvalue, Shooting method, Analytical potential, R-k-r potential.
Classification: 4.3, 16.1.

Nature of problem:
SSM calculates eigenvalues for the radial Schrodinger equation using the recent simplified shooting method.

Solution method:
The search of an eigenvalue is reduced to the search of the zero of a function C(E) with linear shape around its zeros.

Restrictions:
Provided that the data given is valid, there are no known restrictions.

Running time:
Dependant upon the given trial eigenvalue, the number of level and the computer used. 25 seconds for Test run 1 on a 386 personal computer running at 20 Mhz using Microsoft Fortran Compiler.
