Data are presented on the electroproduction reactionse + p ⇒ e + p + Xo⇒ e + &pgr;+ + Xo⇒ e + &pgr;− + X++in the deep inelastic region. The kinematic region covered was0.4 ≤ Q2 ≤ 2.2 (GeV/c)2,2.5 ≤ &ngr; ≤ 7.0 GeV and 4 ≤ s = W2 ≤ 16(GeV)2whereQ2 = electron momentum transfer,&ngr; = 1ab energy loss of the electronands = W2 = invariant (mass)2 of the hadronic final state.
