Observation of Structures in the p p Total Cross-Section Difference of Pure Helicity States in the Mass Range of 2100-MeV to 2500-MeV

We have measured the difference between the pp total cross sections for parallel and antiparallel longitudinal spin states at beam momenta of 1.0, 1.1, 1.30, 1.58, 171, 2.1, and 2.25 GeV/c in a transmission counter experiment. These results reveal new structure in the p/sub lab/ range of 1.0 to 2.5 GeV/c.
