Alpha cluster structure and scattering in 20Ne, 44Ti, 94Mo, 136Te and 212Po

Ndayishimye, Joram (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: We investigate the nuclei 20Ne, 44Ti, 94Mo, 136Te and 212Po using a model of an α-cluster orbiting a closed shell core. A purely phenomenological cluster-core potential is found to provide a successful ...
Characterisation of heavy mineral sands and soils by radiometry and its use in mineral benefication and agriculture

De Villiers, Dawid (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: Radioactivity is well known and well understood, but its usefulness in industrial applications to optimise processes or increase economic viability is not yet fully utilised by many industries. This ...
Characterization of thulium doped fiber for mid infrared laser applications

Ndebeka, Wilfrid Innocent (Stellenbosch : University of Stellenbosch, 2011-03)

Development of a laser cooling and magneto-optical trapping experiment for Rubidium 87 atoms

Rigby, Charles Ian (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: A magneto optical trap (MOT) is capable of trapping a vapor cloud consisting of atoms cooled down to the micro Kelvin range. Three orthogonal pairs of counter-propagating laser beams of the correct ...
Development of a non-collinearly phase matched optical parametric amplifier and application in pump-probe spectroscopy

Rohwer, Egmont J. (Stellenbosch : University of Stellenbosch, 2011-03)

A duality construction for interacting quantum Hall systems

Kriel, Johannes Nicolaas (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: The fractional quantum Hall effect represents a true many-body phenomenon in which the collective behaviour of interacting electrons plays a central role. In contrast to its integral counterpart, the ...
Flattened Gaussian beam for laser paint removal

Du Preez, Neil Carl (Stellenbosch : Stellenbosch University, 2011-03)

ENGLISH ABSTRACT: Lasers are commonly used in the industry for various applications such as laser cutting, laser drilling, lithography, medical applications, surface cleaning and a myriad of other applications. In any ...
Image compression using the one-dimensional discrete pulse transform

Uys, Ernst Wilhelm (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: The nonlinear LULU smoothers excel at removing impulsive noise from sequences and possess a variety of theoretical properties that make it possible to perform a so-called Discrete Pulse Transform, which ...
Numerical modelling of the excitation of polyatomic molecules by femtosecond laser beams

De Clercq, Ludwig Erasmus (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: The selective excitation of an arbitrary vibrational level of a polyatomic molecule, without passage through an intermediary electronic excited state is demonstrated. This was achieved by simulating the ...
Polymer networks with mobile force-applying crosslinks

Mateyisi, Mohau Jacob (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: We construct and study a simple model for an active gel of exible polymer filaments crosslinked by a molecular motor cluster that perform reversible work while translating along the filaments. The ...
