  • Plasma characterisation of an electron cyclotron resonance ion source by means of x-ray spectroscopy 

    Sakildien, Muneer (University of the Western Cape, 2012)
    The ultimate aim of any multiply-charged ion source, like the Electron Cyclotron Resonance Ion Source, ECRIS, is the production of multiply-charged ions, in sufficiently large quantities. These multiplycharged ions, in the ...
  • Point source simulations and Foreground cleaning techniques for HI intensity mapping 

    Ngobese, Sibonelo (University of the Western Cape, 2018)
    We created a full sky point source catalogue at frequencies around 1 GHz, including the intensity, polarisation, rotation measure and spectral index of the point source. These values were matched to data where available ...
  • Polarizability effects due to low-energy enhancement of the gamma-strength function 

    Ngwetsheni, Cebo (University of the Western Cape, 2018)
    Physics is the study of natural phenomena. Nuclear physicists have since the discovery of the nucleus been working on understanding its dynamics. The nuclear chart, analogous to the periodic table of elements, is illustrated ...
  • Post-deposition doping of silicon nanowires 

    Slinger, Jane Bronwyn (University of the Western Cape, 2018)
    Silicon nanowires (Si NWs) continue to demonstrate superior properties to their bulk counterparts, with respect to their morphological and electrical transport properties for the use in photovoltaic (PV) applications. ...
  • Pre-service science teachers’ conceptual and procedural difficulties in solving mathematical problems in physical science 

    Iwuanyanwu, Paul Nnanyereugo (University of the Western Cape, 2014)
    Students frequently leave first-year physical science classes with a dual set of physical laws in mind- the equations to be applied to qualitative problems and the entrenched set of concepts, many erroneous, to be applied ...
  • Probing the large-scale structure of the universe with correlation functions 

    Matshawule, Siyambonga Donald (University of the Western Cape, 2014)
    In this project we explore a new statistical package called KSTAT that computes the 2PCF and higher order correlation functions, such as the 3PCF, on BOSS, making use of high performance computing facilities to improve ...
  • Production of Li, Be and B nuclei in the interaction of 12C with 12C at incident energies of 200 and 400 MeV 

    Mira, Joele Paulus (University of the Western Cape, 2008)
    The objective of this project is to study the production of Li, Be and B isotopes emitted in the interaction of 12C with 12C at incident energies of 200 and 400 MeV.The energies of these produced fragments were measured ...
  • Radio-optical analysis of extended radio sources in the first look survey field 

    Hons, Claudio Moises Paulo (2010)
    I combine 610 MHz Giant Metrewave Radio Telescope (GMRT) data, 1.4 GHz Very Large Array (VLA) data and 1.4 GHz Westerbork Synthesis Radio Telescope (WSRT) observations, encompassing a ∼ 4 square degree field (sq. deg. ...
  • Radiometric study of soil: the systematic effects 

    Joseph, Angelo Daniel (University of the Western Cape, 2007)
    The natural 238U, 232Th and 40K radioactive content of vineyard soil was measured with an in-situ gamma-ray detector. The activity concentrations measured with the in-situ detector are normalized using the laboratory-determined ...
  • Radon escape from water 

    Mvelase, Mashinga Johannes (University of the Western Cape, 2010)
    This thesis aims to measure the rate of radon loss from water in a systematic way. The dependence on surface area, temperature and concentration will be investigated. The experiments were done at UWC by creating radon using ...
  • Radon exhalation of building materials 

    Wentzel, Farrel Sidney (University of the Western Cape, 2018)
    Public concern about all radiation and radon exhalation from building materials has been highlighted recently. The purpose of this study is to address this public concern and to investigate the contribution of building ...
  • Radon in the Cango Caves 

    Nemangwele, Fhulufhelo (University of the Western Cape, 2005)
    Radon is a naturally occurring radioactive element in the 238U decay series that is found in high concentrations in certain geological formations such as Caves. Exposure to high concentrations of radon has been positively ...
  • Redshift-space distortions as a probe of dark energy 

    Gouws, Liesbeth-Helena (University of Western Cape, 2014)
    We begin by finding a system of differential equations for the background and linearly perturbed variables in the standard, ɅCDM model, using the Einstein Field Equations, and then solving these numerically. Later, we ...
  • Signature splitting and inversion in the 186-194 Au Nuclei predicted by the total routhian surface (TRS) and cranked shell model (CSM) calculations 

    Shirinda, Obed (University of the Western Cape, 2007)
    The nearly oblate deformed Au nuclei show rotational bands built on multi quasiparticle excitations [Bou89, Bou92, Gue03, Gue01, Ven92]. Several of these bands are built on rotationally aligned high-j proton and neutron ...
  • Spectroscopy of proton unbound states in 32Cl 

    Kamil, Mohamed (University of the Western Cape, 2019)
    This project aimed to investigate proton unbound states in 32Cl using the 32S(3He; t) charge-exchange reaction. This research is relevant both in the context of nuclear structure and astrophysics. Excited states in 32Cl ...
  • Spin and parity assignment in 152 Gd investigating octupole structures 

    Bvumbi, Suzan Phumudzo (University of Western Cape, 2008)
    The high-spin states of the nucleus 152Gd have been populated via the 152Sm (α, 4n) 152Gd fusion-evaporation reaction at a beam energy of 45MeV. The emitted γ rays were observed with the AFRODITE spectrometer array. The ...
  • Stellar masses of star forming galaxies in clusters 

    Randriamampandry, Solohery Mampionona (University of the Western Cape, 2010)
    We determine the stellar mass of star forming galaxies in the X-ray luminous cluster MS 0451.6-0305 at z ∼ 0.54. The stellar masses are estimated from fitting model spectral energy distributions (SEDs) to deep, optical ...
