Structures in thep¯pandp¯dTotal Cross Sections Between 1.0 and 3.3 GeV/c

Abstract

Three structures are observed in $\overline{p}-p$ and $\overline{p}-d$ total cross sections in a transmission experiment. Two structures, at center-of-mass energies 2190±5 and 2345±10 MeV respectively, are found in the isospin-one state. The third structure, at 2380±10 MeV, is found in the isospin-zero state.
