[en] The International Conference on the Physics of Highly Ionised Atoms at Oxford during July 1984 incorporated the Seventh International Conference on Beam-Foil Spectroscopy. In order to provide continuity with the previous Beam-Foil Conferences, a session - introduced by the two acknowledged pioneers of the technique - was devoted to topical beam-foil experiments and ion-surface interactions. The Oxford meeting, however, accommodated not only current research on interactions between conventionally accelerated particles and solid or gaseous targets but attempted to provoke discussions on a wider range of topical problems involving highly stripped ions. These Proceedings include most of the invited talks as well as contributed papers grouped into six topics viz, collision processes involving highly stripped ions, fundamental problems in atomic structure, novel sources of highly stripped ions, beam-foil spectroscopy, spectroscopy of highly ionised atoms in the laboratory and in astrophysics, and novel aspects of highly ionised atoms.

[en] The present annual report gives a survey of the research activities of the Institute of Nuclear Physics of the University of Frankfurt am Main in 1975. Research was done in the following fields: Investigation of nuclear structures and nuclear reactions with light and heavy ions, atomic collision processes, neutron diffractrometry and neutron spectroscopy, solid state particle track detectors and their application in physics and biology, nuclear methods of analysis and mass spectrometry, ion source development, electronics and data processing, and problems of radiation protection.

[en] This paper presents, for the first time, a systematic study of an optogalvanic method for photoionization spectroscopy. The method is particularly attractive for refractory and complex atoms, such as lanthanides and actinides. The relevant characteristics of the hollow cathode discharges used for this study are discussed in detail, along with the experimental protocol for this spectroscopic method. The rapid optogalvanic effect, which results solely from photoionization, is also described. Finally, we present as an example of the application of this method, a table containing some of the recorded uranium photoionization lines in the 16 300-20 500 cm^-1 range, along with typical samples of the uranium single-colour photoionization spectrum recorded using the rapid optogalvanic technique. A brief discussion of the sensitivity of the rapid optogalvanic effect is also presented. It appears that the rapid optogalvanic effect is very effective in the detection of highly excited levels. This technique permitted the observation of many new single-colour resonant ionization uranium lines. (Author)

[en] A re-investigation of the lifetimes of seven 3p levels, seven 3d levels and one 4 s level of Na II has yielded results in fair agreement with earlier results from Lyon, and in excellent agreement with several calculations. The effect of incorporating data for the cascades in the analysis is demonstrated. (orig.)
