Determination of natural radioactivity concentrations in soil: a comparative study of Windows and Full Spectrum Analysis
(University of the Western Cape, 2004)
In this study, two methods of analysing activity concentrations of natural radionuclides (U, Th and K) in soil are critically compared. These are the Window Analysis (WA) and Full Spectrum Analysis (FSA). In the usual WA ...
Modelling and measurement of radon diffusion through soil application on mine tailings dams.
(University of Western Cape, 2004)
Radon (222Rn) has been identified as an important factor that could result in a health hazard by studies all around the world. The health risks can be minimised by preventive measures where radon is highly concentrated as ...
Linear polarization and lifetime measurement in ¹⁹⁴TL
(University of the Western Cape, 2006)
High-spin states in¹⁹⁴TL were populated using the 181Ta1t8O, 5n) reaction at the beam energies of 91 and 93 MeV during two weekends of beam time. The 1^Tcoincidence data associated with this reaction were measured employing ...
Aluminium induced crystallization of hydrogenated amorphous silicon thin films
(University of the Western Cape, 2005)
This study was carried out to crystallize hydrogenated amorphous silicon (a-Si:H) thin films using the aluminium induced crystallization (AIC) technique. This was done to investigate whether is there any lateral crystallization ...
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 ...
Investigation of stains existing on fossil samples from the sterkfonfein archeaologica sites
(University of the Western Cape, 2006)
It is known that fossilized bone samples excavated from the Sterkfontein archaeological sites have prominent brown stains on their surfaces. Their existence has been postulated by researchers from Transvaal museum to be ...
Spin and parity assignment in 152gd investigating octupole structures
(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 ...
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 ...
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 ...
Using internet -enabled remote instrumentation for research and training in physics: Evaluation of different diffusion barriers for silver metallization
(University of the Western Cape, 2007)
The growth of the Internet has led to many interesting developments for both educational and commercial purposes. In this project an attempt was made to use the Internet for a research purpose to facilitate the determination ...
