  • Mvondo-She, Yannick (University of Pretoria, 2014)
    Recently, was developed a new theory of the Jost function, within which, it was split in two terms involving on one side, singlevalued analytic functions of the energy, and on the other, factors responsible for the ...
  • Vaandrager, Paul (University of Pretoria, 2015)
    A method of extracting resonance parameters from scattering data is outlined for scattering that involves Coulomb interactions. This is done for single-channel scattering, as well as multi-channel scattering. Within the ...
  • Fakira-Du Toit, Hamida Hamida Sarah Jane (University of Pretoria, 2017)
    The main question that has been answered in this research project is: what happens to the singularities of the S-matrix when the interaction potential becomes complex? In other words, we looked at the resonance spectral ...
  • Tshipi, John Tshegofatso (University of Pretoria, 2016)
    The aim of this research is to develop a method for expanding the Jost functions as a Taylor-type power series on the complex angular momentum plane. From this method in conjunction with the Watson transformation, we ...
  • Gopane, Ishmael Mmusi (University of Pretoria, 2015)
    Three-body hypernuclear nn and n systems are studied within the hyperspherical approach framework with local two-body S-wave potentials describing the nn, n and interactions using the Jost functions method. The ...
