Abstracts
The interaction of negative pions and protons has been investigated by Steinberger and co-workers for pions of 85 MeV energy by transmission measurements and by Shutt and co-workers for pions of 55 MeV by direct observation of pion tracks in a Wilson chamber. Both measurements indicate a surprisingly low value for the cross section in this range of energies. We have undertaken to extend the total cross section measurements to higher energies.
