For these kind of measurements we presently depend on the
the various "muon factories" overseas. Some of these facilities
(Zurich), ISIS - Rutherfod Appleton Laboratory (Oxford), and TRIUMF (Vancouver).
The purpose of using the uSR (muon Spin Rotation) technique is -
- The study of the dynamics and chemistry of light positively charged
particles in covalent crystalline insulators. (Also by
, and theotretically using Quantum Chemical and Density Functional Methods).
- To investigate hydrogen behavior in diamond, by analogy with the hydrogenic
analogue atom - muonium. Because the static chemical properties of hydrogen
are very simmilar to those of muonium, uSR studies are able to deliver
extremely important information on hydrogen chemistry in diamond.Hydrogen
catalyses metastable synthetic diamond growth, passivates dopants, affects
the physics and electrical and optical properties.
- The muonium bulk interaction, as well as the interaction with both
natural occuring and ion or radiation induced defects is studied. MSR investigation
of defect configurations in diamond currently focuses on the A and B centres,
and the boron dopant.
Our group includes co-workers from the MSR group based at the MPI fuer
Metallforschung, Institut fuer Physik in Stuttgart, and also Prof. K. Bharuth-Ram
at University of Durban-Westville.
