Abstract:

We analyse the experimental data of Derado and Schmitz on the single pion production process in π^--p collision at 1 Bev by the generalized isobar model. Our isobar model is a generalization of the Lindenbaum and Stenheimer 3-3 nucleon isobar model. But our standpoint is based on the Sakata model and all the possible fermion and boson states of the full symmetry theory are taken into account. It is shown that this generalized isobar model can well explain the experimental momentum spectra. The evidences of boson isobars of I=2 with mass ∼400 Mev and I=1 with mass ∼650 Mev are suggested from the analysis of the D-S data.
