  • Challenges and prospects of teaching the Doppler Effects at grades 12 
    Mupezeni, Sure (2012-02)
    This study focuses on challenges and prospects of the teaching of the Doppler Effect to grade 12 learners. The challenges of teaching the Doppler Effect were established and these findings influenced the development of ...
  • Atomic processes in gaseous nebulae 
    Prozesky, Andri (2011-05)
    The atomic physics relevant to gaseous nebulae is critically examined using modelling software with particular emphasis on radio recombination lines (RRLs). The theoretical spectral line intensities can be deduced if we ...
  • Electromagnetic processes in few-body systems 
    Rampho, Gaotsiwe Joel (2010-11)
    Electromagnetic processes induced by electron scattering off few-nucleon systems are theoretically investigated in the non-relativistic formalism. Non-relativistic one-body nuclear current operators are used with a ...
  • Inverse method in seismology 
    De Villiers, Jean Schepers (2009-11)
    The problem of fitting a material property of the earth to a certain model by analysing a returned seismic signal is investigated here. Analysis proceeds with methods taken from the theory of inverse problems. Seismic ...
  • First year physics practicals in distance education in South Africa 
    Cilliers, Johanna Albertha (1999-11)
    Although the merits of practical work in physics are often questioned, it remains part of physics curricula world-wide. In distance education the incorporation of practical work into the curriculum is considerably ...
  • Hypernuclear bound states with two /\-Particles 
    Grobler, Jonathan (2009-11)
    The double hypernuclear systems are studied within the context of the hyperspherical approach. Possible bound states of these systems are sought as zeros of the corresponding three-body Jost function in the complex ...
  • The impact of interactive-engagement models in the teaching and learning of physics to first year education students 
    Khwanda, Mphiriseni Norman (2009-07)
    The aim of this study was firstly to evaluate the impact of two interactive-engagement models of instruction, namely Whole Class Discussions (WCD) and Computer Simulations (CS) on first year physics student-teachers’ ...
  • Hydrogen and Muonium behaviour in diamond 
    Joseph, Sithole Makgamathe (2009-08-25)
    This work is aimed at the understanding of the dynamical behavior of hydrogen in diamond. The investigation was carried out using Transverse Field muon Spin Rotation (TF-SR) and the Longitudinal Field muon Spin Relaxation ...
  • Shock Excited 1720 MHz Masers 
    De Witt, Aletha (2009-08-25)
    1720 MHz OH masers have been detected towards a number of supernova remnants (SNRs) at the shock interface where the SNR slams into the interstellar medium. Models indicate that these masers are shock excited and can only ...
  • The role of three-body forces in few-body systems 
    Masita, Dithlase Frans (2006-11-30)
    Bound state systems consisting of three nonrelativistic particles are numerically studied. Calculations are performed employing two-body and three-body forces as input in the Hamiltonian in order to study the role or ...
  • Applied inverse scattering 
    Mabuza, Boy Raymond (2009-08-25)
    We are concerned with the quantum inverse scattering problem. The corresponding Marchenko integral equation is solved by using the collocation method together with piece-wise polynomials, namely, Hermite splines. The ...
  • Interaction of the eta-meson with light nuclei 
    De Villiers, Jean Schepers (2009-08-25)
    The long-standing problem of possible formation of metastable states in collisions of the eta-meson with atomic nuclei is revisited. The two-body eta-nucleon interaction is described by a local potential, which is ...
  • A microscopic description of nuclear alpha decay 
    Ogunbade, Olusegun G. (2009-08-25)
    Radioactive decay of nuclei via emission of ??-particles is studied using three different theoretical approaches, viz: the quasi-bound state wavefunction approach (QSWA), the superasymmetric ??ssion model (SAFM) and the ...
  • Dynamics of few-cluster systems. 
    Lekala, Mantile Leslie (2009-08-25)
    The three-body bound state problem is considered using configuration-space Faddeev equations within the framework of the total-angular-momentum representation. Different three-body systems are considered, the main concern ...
  • Artificial neural network methods in few-body systems 
    Rampho, Gaotsiwe Joel (2009-08)
  • A quantum mechanical study of dopants in diamond 
    Lombardi, Enrico Bruno (2009-08-25)
  • Nuclear reactions inside the water molecule 
    Dicks, Jesse (2005-06)
    A scheme, analogous to the linear combination of atomic orbitals (LCAO), is used to calculate rates of reactions for the fusion of nuclei con¯ned in molecules. As an example, the possibility of nuclear fusion in rotationally ...
