Search for tetrahedral bands in yb isotopes
(University of the Western Cape, 2007)Calculations by Dudek et al. predict shell gaps for tetrahedrally shaped nuclei at various proton and neutron numbers. 160Yb is expected to be a favourable nucleus, with tetrahedral bands predicted to lie 1 MeV above the ... -
Signature splitting and inversion in the 186-194 Au Nuclei predicted by the total routhian surface (TRS) and cranked shell model (CSM) calculations
(University of the Western Cape, 2007)The nearly oblate deformed Au nuclei show rotational bands built on multi quasiparticle excitations [Bou89, Bou92, Gue03, Gue01, Ven92]. Several of these bands are built on rotationally aligned high-j proton and neutron ... -
Spectroscopy of proton unbound states in 32Cl
(University of the Western Cape, 2019)This project aimed to investigate proton unbound states in 32Cl using the 32S(3He; t) charge-exchange reaction. This research is relevant both in the context of nuclear structure and astrophysics. Excited states in 32Cl ... -
Spin and parity assignment in 152 Gd investigating octupole structures
(University of Western Cape, 2008)The high-spin states of the nucleus 152Gd have been populated via the 152Sm (α, 4n) 152Gd fusion-evaporation reaction at a beam energy of 45MeV. The emitted γ rays were observed with the AFRODITE spectrometer array. The ... -

(University of the Western Cape, 2008)Spin and parity assignment in 152gd investigating octupole structures The high-spin states of the nucleus ls2cd have been populated via the ls2sm (cr, 4n) 152Gd fusion-evaporation reaction at abeam energy of 45MeV. The ... -
Stellar masses of star forming galaxies in clusters
(University of the Western Cape, 2010)We determine the stellar mass of star forming galaxies in the X-ray luminous cluster MS 0451.6-0305 at z ∼ 0.54. The stellar masses are estimated from fitting model spectral energy distributions (SEDs) to deep, optical ... -
Structural features of air-processible methyl ammonium lead triiodide (MAPbI3) perovskite thin films grown on Al-doped ZnO Nanowire Arrays
(University of the Western Cape, 2023)The performance of air stable, mixed halide (MAPbI3-xClx) perovskite based solar cells is highly dependent on the quality and stability of the perovskite thin film, which in turn, is dependent on the substrate on which it ... -
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 ... -
Study of low-lying proton unbound states in 24Al using the 24Mg(3He; t)24Al reaction.
(University of the Western Cape, 2022)This MSc project entails a study of astrophysically relevant states in 24Al, that are important for a better understanding of the 23Mg(p, )24Al nuclear reaction rate in classical novae. This is a crucial breakout reaction ... -
Study of magnetic properties of nanostructures on self-assembled patterns
(University of the Western Cape, 2010)In the current study, we give a report when oxalic acid was used as an electrolyte to synthesize an AAO template with hexagonal pore array. Optimum parameters were observed as 0.4 M of oxalic acid, anodizing voltage of 45 ... -
A study of neutron pairing correlations using the 136Ba(p, t) reaction
(University of Western Cape, 2020)Observation of neutrinoless double beta decay (0 ) is currently the only means by which one could establish the Majorana nature of neutrinos. Additionally, such an observation would determine the absolute neutrino ... -
A study of SiC thin film layers for electrically conductive diffusion barrier application in Si thin film solar cells.
