Annual Report of the Delegacy lxxvii College by members of the department Dr Lightowlers was on leave of absence at the Bell Telephone Laboratories conducting research project on luminescence in semiconductors Research Professor Price's group continued to develop the field of photoelectron spectroscopy and made considerable progress in extending their studies to the inner electron shells of molecules He organised very successful international conference on photo- ionisation phenomena and photoelectron spectroscopy which was held at Oxford in September The theoretical group under Professor Domb had very profitable year and made many advances in statistical studies of cooperative phenomena Dr Martin developed theories of the distribution of end-to-end lengths of polymer chains Dr Wilkinson made extensive studies on crystals by laser-Raman and far infra-red techniques Dr Sherman constructed 200 ton ram of special design which enabled him to obtain spectra at pressures of 300 000 atmospheres Dr Collins and Dr Davies studied the effect of uniaxial stress on the cathodoluminescence from Zn diffused gallium phosphide in collaboration with They expanded their work on the electrical transport properties of diamond the lumin- escence from Si associated with radiation damage and the spectro- scopic properties of point defects in magnesium oxide Dr Griffiths and Dr Edwards were awarded three- year contract of £14 000 for studies on the Variable Energy Cyclotron and Tandem accelerator at Harwell They continue to maintain flourishing research group on nuclear structural investigations by high energy proton scattering coupled with theoretical work on the nuclear shell model Dr Chapman's group continued their radiophysics and geomagnetic studies full analysis was obtained for the first time of radio signals known as 'whistlers' and new information was obtained on the complex structure and location of magnetospheric ducts and the polarisation spectra of geomagnetic micropulsations Dr Jones continued his studies on atmospherics and the excitation of Schumann resonances in the earth ionosphere cavity Dr Barr made an analysis of radiowave propagation in the high attenuation band 1-4 Hz Conferences visits lectures etc Professor Price lectured at Uppsala Stockholm Oxford London and organised joint conference between the Physical and Chemical Societies on photoelectron spectroscopy Professor Domb lectured in the at Evanston Yeshiva and
