Keywords: Nuclear physics, Theoretical methods, Bound state, Resonant state, Gamow state, Homogeneous lippmann Schwinger equation, Coulomb problem, Coulomb-like potential, Local potential, Nonlocal potential, Separable expansion, Coulomb-sturmian Function, Fredholm determinant, Hypergeometric function, Continued fraction, Chebyshev polynomials. | ||

Classification: 17.16. | ||

Nature of problem:The program calculates bound and resonant state energies and wave functions in local and non-local Coulomb-like potentials. | ||

Solution method:The homogeneous Lippmann-Schwinger equation for Coulomb-like potentials is solved using the potential separable expansion method based on the Coulomb-Sturmian functions. | ||

Restrictions:The built-in potential is the spherical fish bone potential. This, however, can simulate practically all the spherical potentials used in atomic and nuclear physics. | ||

Unusual features:REAL*8 and COMPLEX*16 declarations are used. | ||

Running time:The running time depends mostly on the size of the basis. The test run used about 0.01 seconds cpu time on the Convex C220. |
