Characterisation of natural radioactivity in Karoo Basin groundwater prior to shale gas exploration
(University of the Western Cape, 2017)
The prospect of unconventional shale-gas development in the Karoo Basin (South Africa) has created
the need to obtain baseline data on natural radioactivity in Karoo groundwaters. The Karoo Basin
groundwater radiological ...
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 ...
Synthesis of zinc oxide nanoparticles by a green process and the investigation of their physical properties
(University of the Western Cape, 2017)
Zinc oxide (ZnO) is a wide and direct semiconductor with a wurtzite crystal structure. Its
multifunctionality as the ideal candidate in applications such as blue-UV light emitting
diodes, transparent conducting oxide, ...
Detecting Galaxies in the Epoch of Reionization
(University of the Western Cape, 2017)
The aim of this project was to develop a technique that allows us to measure the redshift
of radio galaxies in the Epoch of Reionization. We achieved this by constructing
a parameterization of the 21-cm absorption feature ...
Coupling of single neutron configurations to collective core excitations in 162Yb using 163Yb
(University of the Western Cape, 2017)
In odd-nuclei the single nucleon can couple to collective excitations of its even-even core
nucleus . These collective excitations lie within the pairing gap and are therefore the
lowest energy excitations of the core. Our ...
Galaxy Clustering as a Probe for Galaxy Evolution in Simulations
(University of the Western Cape, 2017)
Studying clustering on small scales (<10Mpc) over a large span of red-
shifts allows us to connect galaxies to underlying cosmic large-scale
structure, and thereby provide constraints on the physical processes
that drive ...
