Abstract A measurement was made at Fermilab of the difference in the total cross sections between states with beam and target polarizations aligned antiparallel and parallel, {delta}{sigma}{sub {ital L}}={delta}{sigma}({r_reversible})-{delta}({sigma}{sq_bullet}) using 200-GeV/c, polarized proton and antiproton beams and a polarized proton target. This measurement explores the spin dependence of particle interactions and the constituent dynamics. A difference in the spin-dependent total cross sections has been observed in previous experiments at lower energies, and this experiment was the first to explore possible spin effects in {delta}{sigma}{sub {ital L}} at much higher energies. {copyright} {ital 1995 American Institute of Physics.}
