Abstract

The cross section for the fully constrained reaction

ep \to epp \bar{p}

has been determined as a function of the electroproduction variables

Q^{2}

and

s

, in the range

0.7 < Q^{2} < 3

Ge

V^{2}

and

8 < s < 16

Ge

V^{2}

. Evidence is presented and cross-section estimates are made for resonances in the final-state

\bar{p} p

system.
