摘要：

We have measured angular distributions of differential cross sections and analyzing powers (A(y)) of the reaction pp over arrow pointing right --> dpi+ at six incident proton energies between 1.3 and 2.4 GeV. They confirm the rapid variations at square-root = 2.65 GeV suggested by earlier experiments. Deviations from a monotonic behavior are also found in the excitation functions of the differential cross section at t = 0 or where THETA(pi)+ (c.m.) = 0-degrees. Structures clearly appear at square-root s = 2.4 and 2.65 GeV, in some coefficients of the associated Legendre function expansions of A(y).
