Abstract
The and total cross sections were measured on both hydrogen and deuterium at a series of momenta between 360 MeV/c and 720 MeV/c by the transmission method. The data were corrected for Coulomb and decay effects, and the isospin states were extracted. The , cross section was found to be free from resonances, although the presence of a small dip at about 700 MeV/c was confirmed. No convincing evidence was found for structure in the , cross section, which was observed to be steeply rising with increasing momentum throughout this range. The prominence of the was verified in the , system in which no additional structure was seen. In the , system no new structure was clearly established, though there appears to be a small enhancement with a mass about 1600 MeV.
