The spectral Phase-Amplitude representation of a wave function revisited
George Rawitscher
The phase and amplitude (Ph-A) of a wave function vary slowly and monotonically with distance, in contrast to the wave function that can be highly oscillatory. Hence an attractive…
Solution of the Gross-Pitaevskii equation in terms of the associated non-linear Hartree potential
George Rawitscher
The Gross-Pitaevskii equation (GP), that describes the wave function of a number of coherent Bose particles contained in a trap, contains the cube of the normalized wave function,…
Accuracy of a new hybrid finite element method for solving a scattering Schroedinger equation
Joseph Power, George Rawitscher
This hybrid method (FE-DVR), introduced by Resigno and McCurdy, Phys. Rev. A 62, 032706 (2000), uses Lagrange polynomials in each partition, rather than "hat" functions or Gaussian…
Solution of the Schrödinger equation containing a Perey-Buck nonlocality
George H. Rawitscher
The solution of a radial Schrödinger equation for ψ(r) containing a nonlocal potential of the form \int{K(r,r') ψ(r') dr'} is obtained to high accuracy by means of two methods. An…
Evidence of nonlocality due to a gradient term in the optical model
M. I. Jaghoub, G. H. Rawitscher
We demonstrate that the presence of a velocity-dependent term in the phenomenological optical potential simulates a source of nonlocality. This is achieved by showing that, in the…
Novel Source of Nonlocality in the Optical Model
M. I. Jaghoub, M. F. Hassan, G. H. Rawitscher
In this work we fit - elastic scattering angular distributions in the energy range 12 to 20 MeV, by adding a velocity dependent term to the optical potential. Th…
