Nine years in the past, in 1967, a convention on spallation nuclear reactions and their functions in astrophysics was once held on the college of Pennsylvania. I due to the fact that point, a few devel opments have given renewed impetus to the research of spallation reactions. between those are the winning acceleration of excessive power heavy ions within the laboratory and their strength use in melanoma radiotherapy, the supply of back lunar rocks containing documents of previous cosmic-ray irradiation, and the devel opment of the speculation that the spallation of interstellar topic is liable for a lot of the saw common abundances of the infrequent gentle nuclides. In may well 1975, a brand new convention on spal lation nuclear reactions and their functions to astrophysics and radiotherapy used to be prepared and held, back on the college of Pennsylvania. The papers during this quantity are essentially accelerated and up to date types of invited papers given at that convention. To the authors of the papers, we owe a debt of gratitude for his or her contributions and for his or her forbearance. The confer ence itself was once a lot influenced through the providers of the 4 consultation chairmen: William A. Fowler, Serge A. Korff, Robert Serber, and Maurice M. Shapiro, every one of whom has through the years made primary contributions to the subject material of this quantity. an important aid for a lot of the editorial paintings used to be supplied by way of the nationwide Aeronautics and area management and the nationwide technological know-how starting place.
