Abstract

Using a wire-spark-chamber deuteron spectrometer, we have measured the missing-mass (MM) spectrum up to ∼ 1.5 GeV in the reaction

pp \to d + MM

for deutrons produced at 0° in the laboratory and incident momenta of 3.8, 4.5, and 6.3

\frac{GeV}{c}

. Production cross sections for

π

and

ρ

are reported. Evidence of

π_{N} (980)

production with mass 975 ± 6 MeV and width

60_{- 10}^{+ 16}

MeV is presented. No other statistically significant enhancements were found.
