The Course/Workshop on Muon Catalyzed Fusion and Fusion with Polarized Nuclei was held 3–9 April 1987, at the Ettore Majorana School in Erice, Italy. It was attended by about 44 participants, 15 of whom were lecturers. Because of the nature of the two subjects the participants came from a broad range of fields. This was primarily a European workshop, so the majority of the participants were from European countries with a few from other countries. Unfortunately, no one attended from the Soviet Union, where some of the most active research in muon catalyzed fusion is being done.
