We thank Professor P. Preiswerk, H. Schopper and H. Tyrén for their support and interest in this work. Many useful discussions with Professor O. Kofoed-Hansen are gratefully acknowledged and we are particularly indebted to him for putting his unpublished calculations on π4He scattering at our disposal. We thank Dr. W. Beusch for his advice and help during the experimental runs, Dr. V. Chabaud for providing us with the kinematic fitting program used in the analysis, and Mr. R. Lorenzi for his skillful technical assistance.
