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 ...
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 ...
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 ...
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 ...
New Collective structures in the Z=76 stable odd neutron nucleus, 187Os
(University of the Western Cape, 2021)
Low- and medium-spin bands of 187Os have been studied using the AFRODITE array, following the 186W(4He,3n)187Os reaction at a beam energy of 37 MeV. The measurements of γ − γ coincidences, angular distribution ratios (RAD), ...
Imprints of Primordial Non-Gaussianity on Large Scale Structure in the Universe
(University of the Western Cape, 2016)
Large scale structure in the universe is one of the most important probing tools for
cosmological modelling. Assuming the hot big bang model of the universe, the expansion
history has undergone two phases of acceleration. ...
A large-scale clustering analysis of radio galaxies
(University of the Western Cape, 2019)
The distribution of the visible structure in the Universe is in part dependent on the
in
uence of the dark matter structure. Measurements of large-scale structure can
therefore be related to the dark matter distribution ...
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 ...
Feasibility of Nuclear Plasma Interaction studies with the Activation Technique
(University of the Western Cape, 2018)
Electron-mediated nuclear plasma interactions (NPIs), such as Nuclear Excitation
by Electron Capture (NEEC) or Transition (NEET), can have a signi cant impact
on nuclear cross sections in High Energy Density Plasmas (HEDPs). ...
Determining the Spectroscopic Quadrupole Moment Qs of the 2+1 state in 40Ar
(University of the Western Cape, 2017)
The rst reorientation-e ect Coulomb-excitation experiment has been
performed at iThemba LABS by bombarding 40Ar beams on a heavy
208Pb target at a \safe" energy of Elab =143.2 MeV. The goal was to
determine, the spectroscopic ...
