Abstract：
In this paper, a two-nucleon absorption model for pions at rest is extended todiscuss the nucleon spectra after absorption of pions of a few nundred MeV energies.Nucleon spectra emitted afte 220 MeV pion absorption by ¹²C, ⁵⁸Ni and ¹⁸¹Ta are cal-culated. The A dependences of the absorption cross section, the mean number ofnucleons N emitted after pion absorption and the ratio of the yields of protons from π⁺ v.s. π absorption can be well described by two-nucleon mechanism.
