Abstract：
Some experimental data in p-Be collisions at 19GeV/c with the E864/E941 spectrometer at the Alternating Gradient Synchrotron(AGS) has been analyzed. The invariant mass distribution of leading Λ and Δ⁺⁺ in p-Be collisions at 19GeV/c is presented with a new iterative algorithm through studying distribution of the pairs of proton and pion.
