Peripherals: disc. | ||

Keywords: Nuclear physics, Theoretical methods, Scattering state, Inhomogeneous lippmann Schwinger equation, Coulomb problem, Coulomb-like potential, Local potential, Nonlocal potential, Separable expansion, Coulomb-sturmian Function. | ||

Classification: 17.16. | ||

Nature of problem:The program calculates scattering state phase shifts and wave functions in local and nonlocal Coulomb-like potentials. | ||

Solution method:The inhomogeneous Lippmann-Schwinger equation of Coulomb-like potentials is solved using the 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 took about 0.01 seconds on the Convex C220. |
