Nuclear level densities and gamma-ray strength functions in Ta isotopes and nucleo-synthesis of ¹⁸ᴼTa
(University of the Western Cape, 2016)Most stable and extremely low abundance neutron deficient nuclei with Z ≥ 34 are referred to as p-nuclei. Nearly all p-nuclei with A < 110 are most likely produced in the rp-process while almost all A > 110 are thought ... -
Octupole and quadrupole structures in the N=88 nucleus 152Gd
(University of the Western Cape, 2018)The focus for this work is on 152Gd produced by the 150Sm( , 2n)152Gd reaction at a beam energy of 25 MeV. The nucleus has been previously studied for both low spin states and high spin states at di erent energies. The ... -
Optical emission spectroscopy of laser induced plasmas containing carbon and transitional metals
(University of the Western Cape, 2008)The spectroscopic, SEM and Raman measurements on carbon nanotubes under the exact conditions of which OES analysis were made showed that at a pressure of 400 Torr and a flow rate of 200 sccm, the quality and quantity of ... -
Optical properties of annealed hydrogenated amorphous silicon nitride (a-SiNx:H) thin films for photovoltaic application
(2013)Technological advancement has created a market for large area electronics such as solar cells and thin film transistors (TFT’s). Such devices now play an important role in modern society. Various types of conducting, ... -
Optimization of lead halide perovskite thin films by chemical vapour deposition
(University of Western Cape, 2021)Perovskite solar cells have gained tremendous attention within the past decade, due to its rapid improvement in power conversion e ciency (PCE), with the current record cell at 25%. The aim of this study is to create ... -
Out of thermodynamic equilibrium reaction of zinc-molybdenum system monitored by real-time rutherford backscattering spectrometry
(University of the Western Cape, 2022)Solid phase reaction of bi-metallic thin films of zinc-molybdenum was thermally induced in order to investigate the diffusion kinetics of this bi-metallic system. The Zinc-Molybdenum bilayers were prepared by depositing ... -
(p.n.) Reactions on 59co in the intermediate energy range
(University of the Western Cape, 1992)Detailed theoretical investigations [Chi80,Mos82,Kle85] of (p,n) and (p,p') data indicate that the reaction mechanisms operative at intermediate energies and for energy losses up to several tens of MeV are predominantly ... -
Photo-physical properties of lead-tin binary Perovskite thin films
(University of Western Cape, 2021)Organic-inorganic lead-based perovskite has exhibited great performance in the past few years. However, the lead (Pb) embedded in those compounds is a significant drawback to further progress, due to its environmental ... -
Plasma characterisation of an electron cyclotron resonance ion source by means of x-ray spectroscopy
(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
