Calibration of germanium detectors for applications of radiometric methods in South Africa.
(University of the Western Cape, 2001)
AII materials that are radioactive emit characteristic gamma-radiation. Natural radioactivity
can be used in heavy minerals exploration and processing, as well as in understanding
sediment transport. processes in coastal ...
Intense pulsed neutron generation based on the principle of plasma immersion ion implantation technique (PIp3s) technique
(University of the Western Cape, 2006)
The development of a deuterium deuterium/ tritium-deuterium (D-D/ D-T) pulsed neutron generator based on the principle of the Plasma Immersion Ion Implantation 1Pl) technique is presented, in terms of investigating development ...
Study of the use of Electret Ion chambers as radom dosimeters in South Africa
(University of the Western Cape, 2002)
Radon is a naturally occuring radioactive gas which has been shown to be a major contribution to background dose. The underground mines in South Africa present a major occupational hazard. A need for cheap personal monitoring ...
(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 ...
A case study of university students' experiences of introductory physics drawn from their approaches to problem solving
(University of the Western Cape, 2001)
This thesis explores the experience of leaming physics through a particular medium: problem-solving, which is seen by many educators as the primary medium in which physics is learnt at university. Situating itself within ...
Inclusive (p, α) and (p,³He) cross sections induced by 100 MeV protons on ⁴⁰Ca
(University of the Western Cape, 2006)
Alpha clusteri ng in nuclei is studied with quasi - free knockout reactions. A beam of 100 MeV polarized protons was used in the quasi-free knockout reaction 40 ~a( p,p' a)36 Arat iThemba LABS. While the scattered protons ...
Machine learning approaches to study star formation and black hole accretion in the Meerkat/MIGHTEE survey
(University of the Western Cape, 2023)
Galaxy formation and evolution are driven by two main physical processes: star formation and black hole accretion. Both processes can be traced via the synchrotron emission at radio wavelengths. However, a reliable ...
Physics graduate preparedness for work and society
(University of the Western Cape, 2023)
Both internationally and in South Africa, there have been renewed debates about the purposes of higher education and the attributes that should be developed in graduates. In the field of physics, many studies have reported ...
Carbon, magnesium implantation and proton irradiation on pulsed laser deposited thermochromic thin film of VO2
(University of Western Cape, 2020)
When the spacecrafts orbit in space, it is subjected to significant thermal cycling variation. Thermal regulation of the spacecraft temperature is required to ensure a good
operation of the small crafts such as CubeSats ...
Measurements and applications of radon in South African aquifer and river waters
(University of the Western Cape, 2009)
In the natural decay series of 238Uan inert radioactive gas, 222Rn(radon) is formed in the decay of 226Ra.Because radon is relatively soluble in water, it migrates from places of its generation in rocks and soils to other ...
