Abstract

We have studied the reaction p+p→p+p+

π^{0}

, near threshold, at five energies between 320 and 500 MeV, by detecting the decay γ rays of the

π^{0}

in coincidence in two large NaI crystals. The

π^{0}

energy and angular distributions were measured from which we determine that the s-wave contribution to the total cross section is

σ_{T s}^{S}

(μb)=(15.2±3.0)

η_{0}^{2}

. This is somewhat lower than results of previous experiments.
