Under current investigation is the re-implementation of the Distorted-Wave Impulse Approximation (DWIA),
originally formulated in FORTRAN by N.S. Chant and P.G. Roos, with the intention of developing it in a
portable Python environment. This will be complimented by developing a GEANT4 detector simulation application.
These two techniques will be used to model the (p,2p) proton knock-out reaction 40Ca(p; 2p)39K (2.52
MeV)1
2
+ first excited state, at intermediate incident energies of 150 MeV. This study is a test-bed that lays the
foundation and platform from which one may develop an interactive workbench and toolkit in GEANT4 which:
(i.) accurately models an accelerator-detector experimental set-up, such as those found at iThemba Labs, and
(ii.) incorporates the DWIA formalism as a built-in physics process within the framework of GEANT4.
Furthermore the Python modules developed for the specific proton knock-out reaction studied here, can be generalized
for an arbitrary set of nuclear scattering reactions and packaged as a suite of scientific Python codes. / Theoretical and Computational Nuclear Physics / M. Sc. (Theoretical and Computational Nuclear Physics)
