This volume comprises a collection of invited papers presented at the interna tional symposium "The Future of Muon Physics", May 7-9 1991, at the Ruprecht Karls-Universitat in Heidelberg. In the inspiring atmosphere of the Internationales Wissenschaftsforum researchers working worldwide at universities and at many inter national accelerator centers came together to review the present status of the field and to discuss the future directions in muon physics. The muon, charged lepton of the second generation, was first oberved some sixty years ago~ Despite many efforts since, the reason for its existence still remains a secret to the scientific community challenging both theorists and experimentalists. In modern physics the muon plays a key role in many topics of research. Atomic physics with negative muons provides excellent tests of the theory of quantum electrodynamics and of the electro-weak interaction and probes nuclear properties. The. purely leptonic hydrogen-like muonium atom allows tests of fun damental laws in physics and the determination of precise values for fundamental constants. New measurements of the anomalous magnetic moment of the muon will probe the renormalizability of the weak interaction and will be sensitive to physics beyond the standard model. The muon decay is the most carefully studied weak process. Searches for rare decay modes of muons and for the conversion of muonium to antimuonium examine the lepton number conservation laws and new speculative theories. Nuclear muon capture addresses fundamental questions like tests of the CPT theorem.
This volume contains papers which have been presented at the International Sym posium on Metal Clusters in Heidelberg from April 7-11, 1986. Clusters, and in particular metal clusters, have been the topic of fa t growing scientific interest. Indeed, clusters constitute a field of interdisciplinary nature where both physical and chemical questions have to be addressed. Clusters are offundamental importance for the deeper understanding of the transition from atoms via molecules and larger aggregates of particles to the properties of solid materials. Moreover, metal clusters and their character istics are of vital significance for such applied topics as catalysis or photography. Experimentally, the field exhibited rapid progress in the last years. Different sources for clusters have been developed. Intense beams made possible the investigation of free neutral clusters and cluster ions as well. Even though a number of issues concerning metal clusters is still discussed controversially, the present volume tries to give an overview of current work in this field and to illustrate the large variety of experiments as well as the advances made possible by modern theoretical methods. Looking at the many interesting questions still to be addressed it is fair to propose a rapid further growth of this field."
Das 600jahrige Jubilaum der Ruprecht-Karls-Universitat Heidelberg war An- lass, im vorliegenden Bericht der Klinik$-und Abteilungsdirektoren die medizi- nischen Kliniken, der Universitat zu beschreiben und ihre Leistungen darzustel- 'len. In der Tat tragt die klinische Medizin nicht nur wesentlich zur Ausstrah- lung und zum weltweiten Ruf der Universitat bei, sondern stellt auch - auf- grund ihres Gesamtvolumens an Kosten und Personal - einen wesentlichen Faktor der heutigen Universitat dar. Zusammen mit dem Klinikum der Uni- versitat Heidelberg in Mannheim werden hier nahezu 4000 stationare Platze bereitgestellt. Allein im Heidelberger Klinikum sind 6000 Beschaftigte um die Heilung der Kranken bemuht. So stellen die Klinika der Universitat Heidel- berg heute das groesste Zentrum universitarer Krankenversorgung in der Bun- desrepublik dar. Die Medizin hat in Heidelberg eine lange Tradition. Praktisch seit Beginn der Universitat wurde sie hier gelehrt, wenn auch mit unterschiedlicher Intensi- tat. Seit der Universitatsreform Ottheinrichs im Jahre 1558 wurden die Metho- denhumanistischer Wissenschaft auch in die Medizin eingefuhrt. Mit dem Fortschritt naturwissenschaftlicher Forschung, vor allem in der Botanik und der Chemie, kamen aus diesen Wissenschaften entscheidende Impulse fur die Entwicklung der Medizin. So wirkte z. B. der Anatom und Physiologe Johann Conrad Brunner als therapeutisch tatiger Arzt wegweisend fur seine Wissen- schaft, indem er seinen Studenten botanisches Grundwissen vermittelte und sich um ein chemisches Labor bemuhte. Er wurde im ubrigen mit der Entdek- kung der Drusen des Zwoelffingerdarms bekannt.
