The imaginary part of the helicity nonflip C = -1 exchange amplitudes in elastic scattering between 6 and 14 GeV

Using accurate data on the differential cross sections for elastic scattering of particles and antiparticles on protons from 6 to 14 GeV, the projection of the C = -1 exchange amplitude onto the dominant diffractive amplitude is measured. Strong peripherality in impact parameter space is observed for all the measured amplitudes with peak values scaling with the interaction radius. The zero of the imaginary part of the C = -1 exchange amplitude in K+-p scattering moves to smaller t values as the energy increases from 6 to 14 GeV. The p+-p exchange amplitude is more peripheral than the π+-p and K+-p counterparts and an unexpected energy dependence is observed. (Auth.)
