Results from a coincidence measurement of the 16O(̂>+, ̂>+̂>-) &=280 MeV are reported, the first of this class. The energy- and angular-integrated cross section was found to be 2950±̂>450 ̂>b and is compared with theoretical predictions. Low-energy positive-pion intensities are found to be much higher than those yielded by a four-body phase-space calculation. © 1987 The American Physical Society.
