Abstract

The charge-exchange reaction

pp \to n Δ^{+ +} (1236)

has been systematically analyzed up to 24.2 GeV/c to test the concept of dominance in the

t

channel by high-lying Regge trajectories at very high energies. The results provide clear evidence for no more than pion exchange up to the highest momentum studied.
