dc.description.abstract	Joint Supervisors: Dr Grenville Mason and Dr Arthur Olin. A recurring feature in the global analysis of pionic X-ray data has been the anomalous width of the n-Na 2p-ls X-ray. Previous experimental data has shown widths of up to 12KeV, whilst optical model calculations predict values no smaller than 17KeV. In order to resolve this discrepancy another measurement has been made using a newly-developed Compton suppression spectrometer. The performance of the suppression system with sources and in beam, is reported. The resulting reduction of the continuum Compton background by a factor of about 5 at the energy of the X-ray, has allowed a more confident determination of the X-ray width and energy. The values obtained are: πNa 2p-ls X-ray: Energy= 276.2(O.9)KeV Width= 16.7(3.l)KeV
