Muonic Atoms and Molecules

From Sunday evening, April 5, until Thursday afternoon, April 9, 1992,49 scientists from 10 countries met at the Centro Stefano Franscini on Monte VeritA overlooking Ascona, in the state of Ticino in Switzerland, for an international workshop on Muonic Atoms and Molecules. More than two-thirds of the participants presented their results in talks of 20 to 40 minutes' duration. In addition, Prof. Gabriele Torelli gave, under the patronage of the Ministro del Ambiente of the state of Ticino, Dr. Mario Camani, a lecture in Italian entitled "Un modo insolito di studiare Ie proprieta nucleari, atomiche e chimiche". The scientific program commenced on Monday morning with discussions centering on nuclear muon capture and nuclear fusion and fission, moving on to muonic atom spectroscopy in the afternoon. All of Tuesday was devoted to muon catalyzed fusion and muon transfer. On Wednesday morning, different aspects of hot muonic atoms were discussed, followed by informal gatherings in the afternoon and evening. On Thursday morning we took a look at the prospects for the TRIUMF and PSI meson factories, and new experimental methods. The conference was brought to a close in the afternoon with C. P. summarizing the events of the past days. The two organizers want to thank all participants for their contributions and for the lively discussions which often followed the different talks.
