Abstract

Elastic scattering of

\bar{p}

p

has been studied for

{cos θ}_{c . m .}

between -0.88 and -1.0 and

P_{lab} (\bar{p})

between 0.70 and 2.16 GeV/c. The momentum dependence of the cross section shows a sharp dip at 0.9 GeV/c and a broad peaking around 1.4 GeV/c. The possibility of the peak resulting from direct formation of boson resonances has been studied. Alternatively, a diffraction model agrees qualitatively with our data and other elastic data at different angles.
