Proposal to study pi -p reactions at 60 and 200 GeV/c in the 30 inch hydrogen bubble chamber at NAL

A request is made for 50,000 photographs of 60 GeV/c {pi}{sup -} and 50,000 photographs of 200 GeV/c {pi}{sup -} in the Argonne 30 inch hydrogen bubble chamber at NAL. Reasons are given explaining how good physics can be done with this chamber. This experiment is a natural extension of the work of the group and will be of great usefulness in preparing for experiments with the CERN II accelerator.
