Abstract

The deep-inelastic double-charge-exchange reaction ${}^{16}O (π^{+}, π^{-})$ has been measured at 50°, 85°, and 130° with 240-MeV incident pions. The doubly differential cross section is peaked at low outgoing pion energies, as is expected from a double-scattering process, and is nearly isotropic. The integrated cross section is 5.8±0.9 mb. The shape of the differential cross section suggests that the low-energy tail in ${}^{16}O (π^{+}, π^{+'})$ scattering at the same energy also arises from double scattering.
