Abstract:
The ion beam analysis (IBA) techniques of Rutherford backscattering 
spectrometry (RBS), nuclear reaction analysis (NRA), heavy-ion elastic 
recoil detection analysis (HI-ERDA) and particle-induced X-ray emission 
(PIXE) have been used with i) a static ion milli-beam and ii) a position 
scanned ion micro-beam to profile i) the elemental composition in one 
dimension and ii) molecular diffusion in two dimensions in a variety of 
materials. The techniques will be discussed and their application to, for 
example, the profiling of N in GaAs1-xNx thin films, water diffusion into 
drug-release polymers and fibre optic pressure sensors as well as hair dye 
into hair will be described.
