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 ...
New bands in ¹⁹²Tl using gamma spectroscopy techniques
(University of the Western Cape, 2011)
High spin excited stats in¹⁹²Tl were studied using gamma-ray spectroscopy. The study included taking an active part in performing the experiment, understanding the experimental procedure, electronics and data acquisition ...
Calibration of a NaI (Tl) detector for low level counting of naturally occurring radionuclides in soil
(University of the Western Cape, 2011)
The Physics Department at the University of the Western Cape and the Environmental Physics group at iThemba labs have been conducting radiometric studies on both land and water. In this study a 7.5 cm X 7.5 cm NaI (Tl) ...
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 ...
Comparison of neutron fluence spectra measured with NE213 proton recoil spectrometer and NE230 deuteron recoil spectrometer
(University of the Western Cape, 2014)
A (5 cm × 5 cm) cylindrical NE213 liquid organic scintillator and a (2.5 cm × 2.5 cm)cylindrical NE230 liquid organic scintillator were used as spectrometers. A series of measurements was made with both the NE213 and NE230 ...
Vertically aligned silicon nanowires synthesised by metal assisted chemical etching for photovoltaic applications
(University of the Western Cape, 2015)
One-dimensional silicon nanowires (SiNWs) are promising building blocks for solar cells as they provide a controlled, vectorial transport route for photo-generated charge carriers in the device as well as providing ...
Developing a sorting code for Coulomb excitation data analysis
(University of the Western Cape, 2015)
This thesis aims at developing a sorting code for Coulomb excitation studies
at iThemba LABS. In Coulomb excitation reactions, the inelastic scattering
of the projectile transfers energy to the partner nucleus (and ...
Laser drilling of metals and glass using zero-order bessel beams
(University of the Western Cape, 2013)
This dissertation consists of two main sections. The first section focuses on generating zero order Bessel beams using axicons. An axicon with an opening angle y = 5⁰ was illuminated with a Gaussian beam of width ω₀ = 1.67 ...
Analysis and simulations to obtain the weak magnetism term in ²²Na beta decay
(University of the Western Cape, 2016)
The study of ²²Na beta decay offers an opportunity to test the Standard Model of Particle Physics via measurements of the β−γ angular correlation. A previous measurement of this correlation yielded a non-zero value, ...
A theoretical study of stellar pulsations in young brown dwarfs
(University of the Western Cape, 2011)
This thesis reports the results of a twofold study on the recently proposed phenomenon of 'stellar pulsations' in young brown dwarfs by the seminal study of Palla and Baraffe (2005) (PB05, thereafter). The PB05 study ...
