Inclusive pion single-charge-exchange reactions

The (${\pi }^{+}$,${\pi }^0$) and (${\pi }^{-}$,${\pi }^0$) reactions were studied on a variety of nuclei at a bombarding energy of 160 MeV. The full ${\pi }^0$ energy spectra were measured with a ${\pi }^0$ spectrometer at several detection angles. The energy spectra and angular distributions are characteristic of quasifree reactions. Effects due to multiple scattering, neutron screening, and Pauli blocking are clearly observed.
