lxxxvi Annual Report of the Delegacy In addition to the grants listed on xiii Dr Wilkinson received jointly with Professor Style grant of £50 000 from the for work on far infra-red spectroscopy using interferometers and £10 000 towards the purchase of an ionised argon laser for Raman spectroscopy Professor Price and Dr Wilkinson received grants from the Army European Research Office of £2 500 from the Institute of Petroleum of £850 and from £385 for spectroscopic work Professor Champion and Dr Lightowlers received £1 025 from Industrial Distributors Ltd for research on diamond and Dr Lightowlers an grant of £9 475 for studies of intra-red photo- conductivity in semi-conductors Royal Society grant of £5 156 for investigations of acceptor and donor levels in semi-conductors and £495 from the Central Research Fund for luminescence studies of radiation damage in diamond Professor Domb had his Army grant of £3 700 renewed Dr Jones was given grant of £702 from the Central Research Fund towards the development of an in- strument for tracking Schumann Resonances Research Professor Price's group constructed new high-resolution photoelectron spectrometer which has already solved many fundamen- tal problems New high-energy sources were also developed which permit the study of the inner electron shells of molecules Dr Wilkin- son continued his studies of inter-molecular vibrations in solids and liquids by far infra-red and Laser Raman spectroscopy and Dr Sherman made further experiments on the effects of high pressures on the vibrations of polyatomic ions isolated in crystalline matrices Professor Champion Dr Lightowlers and Dr Collins made extensive studies of the optical and electrical properties of natural and synthetic diamond and the effect on these of the introduction of impurities by ion implantation Other materials which they are investigating include silicon gallium phosphide and magnesium oxide Dr Martin and Dr Sykes directed the theoretical group in Professor Domb's absence They continue to apply statistical methods in the interpretation of co-operative and critical phenomena Dr Chapman and Dr Jones extended their electromagnetic propaga- tion investigations from the study of geomagnetic micropulsations with periods of 100 seconds to the recording of cosmic radio noise at MHz wide range of experimental projects on the propagation of atmo- spherics in the ionosphere is under way and to facilitate this work much new instrumentation was constructed including for example
