Calculation of the Two-body T-matrix in Configuration Space
George Rawitscher
A spectral integral method (IEM) for solving the two-body Schroedinger equation in configuration space is generalized to the calculation of the corresponding T-matrix. It is found…
An economical method to calculate eigenvalues of the Schroedinger Equation
G. H. Rawitscher, I. Koltracht
The method is an extension to negative energies of a spectral integral equation method to solve the Schroedinger equation, developed previously for scattering applications. One imp…
Three-atom scattering via the Faddeev scheme in configuration space
W. Gloeckle, G. Rawitscher
Faddeev equations in configuration space and integral form for three-atom scattering processes are formulated allowing for additive and nonadditive forces. The explicit partial wav…
Towards exact variational Monte-Carlo calculations in light nuclei
Q. N. Usmani, G. Rawitscher, A. Singh
This paper is being withdrawn by the authors in order to correct some errors and also to introduce improved theoretical techniques.
An accurate spectral method for solving the Schroedinger equation
G. H. Rawitscher, I. Koltracht
The solution of the Lippman-Schwinger (L-S) integral equation is equivalent to the the solution of the Schroedinger equation. A new numerical algorithm for solving the L-S equation…
