TEST OF TIME-REVERSAL SYMMETRY IN THE PROTON DEUTERON SYSTEM

Internal target experiments with high-quality proton beams allow for a new class of experiments providing null tests of time-reversal symmetry in forward scattering. This could yield more stringent limits on T-odd P-even observables. An excellent candidate for such experiments is the proton-deuteron system. This system is analyzed in terms of effective T-violating P-conserving nucleon-nucleon interactions and bounds on coupling strengths that might be expected are given.
