The aim of this proposal is to examine the relative population of sp2 and sp3 bonds in a small number of graphitic samples, given that the bond length is 1.42A for standard sp2 bonding (typical for graphites) and 1.54A; for sp3 bonds (the value for diamond has been used here) in carbons. By applying the full Q range of the GEM spectrometer to derive the C-C pair correlation function with the optimum resolution, we hope to be able to distinguish peaks arising from each of these bonds and hence that it will be possible to identify the presence of sp3 bonding in radiation-damaged graphites, specifically a high temperature Magnox-irradiated radiation damaged graphite and a low temperature Gleep radiation damaged graphite. A vitreous carbon known to contain a large proportion of sp3 bonded carbon will also be studied, along with a pristine PGA graphite.
