Contribution of the "hanged" diagrams into the reaction $np \to np π^+
π^-$    [PDF]

A. P. Jerusalimov

The contribution of "hanged" diagrams into the reaction $np \rightarrow np \pi^+ \pi^-$ was considered. It was shown that taking into account of these diagrams permits to get better description of the effective mass spectrum of $\pi^+\pi^-$-combinations.
