title = "Isotopic effects in the (π±, 2N) reactions on 16O and 18O",
abstract = "The (π+, 2p), (π+, pn) and (π-, pn) reactions on 16O and 18O were studied at 165 MeV. The cross section for the (π+, 2p) reaction on 18O is larger than that for 16O be only 5% ± 3%, while the total π+ absorption cross section is larger by 17% ± 5%. This supports the assumption that two-nucleon absorption occurs mainly on nucleons in the same shell. It is further concluded that Δ++n → pp is not only absorption mechanism that couples strongly to the nucleon knock out reactions.",
