Results are reported from a hybrid experiment designed to search for backwards-produced charge = + 2 exotic meson resonances by investigating the reaction π+ + p → X++ + n (forward) at 8.4 GeV/c. The data reported here correspond to approximately 30 events per microbarn. No clear evidence for narrow exotics mesons was found for masses ≤ 3.0 GeV in the decay modes accessible for study which included: X++→π+π+, π+π+π+π-, π+π+π+π+π-π-, and ppπ+π+.
