We have studied the interactions of 400-GeV/c protons with beryllium nuclei and observed hadrons produced at large transverse momenta (p_⊥) back to back near 90^∘{} in the proton-nucleon center-of-momentum system. When both transverse momenta exceed about 2.6 GeV/c, we observe that the probability per single hadron of observing a second high-p_⊥ hadron on the opposite side approximately scales in the ratio of the two transverse momenta (xₑ scaling). Quantum-number correlations between the opposite-going high-p_⊥ hadrons are weak.
