Modelling and measurement of radon diffusion through soil application on mine tailings dams.
(University of Western Cape, 2004)Radon (222Rn) has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as ... -
Determination of the Spectroscopic Quadrupole moment of the first 2+ excited state in 32S
(University of the Western Cape, 2019)In this work we have determined the spectroscopic or static quadrupole moment of the rst excited state (QS (2+1) lying at 2230.6 keV in 32S using the reorientation e ect. The Coulomb-excitation experiment at safe ... -
Structural properties and optical modelling of SiC thin films
(University of the Western Cape, 2020)Amorphous silicon carbide (a-SiC) is a versatile material due to its interesting mechanical, chemical and optical properties that make it a candidate for application in solar cell technology. As a-SiC stoichiometry can be ... -
Cosmology with HI intensity mapping: effect of higher order corrections
(University of the Western Cape, 2020)One of the main challenges of cosmology is to unveil the nature of dark energy and dark matter. They can be constrained with baryonic acoustic oscillations (BAO) and redshift space distortions, amongst others. Both have ... -
Reconstruction of the ionization history from 21cm maps with deep learning
(University of the Western Cape, 2020)Upcoming and ongoing 21cm surveys, such as the Square Kilometre Array (SKA), Hydrogen Epoch of Reionization Array (HERA) and Low Frequency Array (LOFAR), will enable imaging of the neutral hydrogen distribution on ... -
A study of SiC thin film layers for electrically conductive diffusion barrier application in Si thin film solar cells.
(University of the Western Cape, 2019)Semiconductor silicon carbide (SiC) thin films of different thicknesses were deposited by electron beam physical vapour deposition (EBPVD) for application as diffusion barrier application to guard against metal contaminants ... -
High resolution gamma-spectroscopy of environmental samples
(University of the Western Cape, 2019)In this study, a comparison has been made between the available commercial software package Genie 2000 developed by Canberra and Virtual Gamma Spectroscopy Laboratory (VGSL) developed by the Radionuclide Development Unit ... -
Probing the primordial Universe using the SKA in combination with other cosmological surveys
(University of the Western Cape, 2019)Next-generation surveys of the large-scale structure of the Universe will be of great importance in allowing us to extract invaluable information about the nature of the Universe and the physical laws that govern it, at ... -
Detecting Baryon Acoustic Oscillations with HI Intensity Mapping using MeerKAT
(University of the Western Cape, 2019)Future radio surveys as the Square Kilometer Array (SKA) and its precursor, the "Meer" Karoo Array Telescope (MeerKAT), will map the Neutral Hydrogen (HI) in large areas of the sky using the intensity mapping (IM). HI ... -
Determining the spectroscopic quadrupole moment of the first 2+ state in 36Ar
(University of the Western Cape, 2019)A series of reorientation-effect Coulomb-excitation experiments were carried out at iThemba LABS from April to May 2016. Enriched ion beams of Ar, Ar and S were bombarded at safe energies, well below the ... -
A study of the angular momentum content of early-type galaxies

Design of a helium-6 production target for the iThemba LABS Radioactive-ion Beam Facility
(University of the Western Cape, 2018)It is well known, that there is a severe lack of information available pertaining to neutron rich nuclei, specifically of those nuclei with mass numbers ≥ 60. These neutron rich nuclei are not easy to access in current ... -
Testing gravity with redshift-space distortions, using MeerKAT and the SKA
(University of the Western Cape, 2019)The growth rate of large-scale structure is a key probe of gravity in the accelerating Universe. Standard models of Dark Energy within General Relativity predict essentially the same growth rate, whereas Modified Gravity ... -
Radon exhalation of building materials
(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 ... -
Testing the statistical isotropy of the universe using radio survey data
(University of the Western Cape, 2019)The Cosmological Principle forms part of one of the most fundamental hypotheses of modern Cosmology. So it is very important to assess whether it holds true using observational data, or whether it consists of a mathematical ... -
Determining the observer’s velocity using radio continuum surveys
(University of the Western Cape, 2019)In the standard (‘concordance’) model of Cosmology, there is a fundamental assumption that the Universe is statistically isotropic and homogeneous on large scales, known as the Cosmological Principle. The Cosmological ... -
Characterisation of the first 1/2+ excited state in 9B and isospin symmetry breaking studies in A = 9 nuclei
(University of the Western Cape, 2019)The 9Be - 9B isospin doublet carries fundamental significance for both nuclear structure and nuclear astrophysics studies. The first excited 1/2+ state in 9Be is already well established. However, its isobaric analogue ... -
Metal assisted chemically etched silicon nanowires for application in a hybrid solar cell
(University of the Western Cape, 2018)Photovoltaic (PV) devices based on inorganic-organic hybrid active layers have been extensively studied for over a decade now. However, photoactive hybrid layers of material combinations such as rr-P3HT and SiNWs still ... -
Nonlinear optical properties of natural dyes based on optical resonance
(University of the Western Cape, 2012)Recent research shows that the study of optical properties of organic material natural dyes has gained much consideration. The specific functional groups in several natural dyes remain essential for the large nonlinear ... -
Polarizability effects due to low-energy enhancement of the gamma-strength function
(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 ...
