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...

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...
