Study of the Reactions 9Be(p, π-)10C and 12C(p, π-)13O at 613 MeV
Abstract
Negative-pion production leading to discrete excitation levels of the residual nucleus has been investigated on 9Be and 12C targets with 613-MeV protons. On the first seen spectra of 13O a strong excited peak is observed at 2.82 -/+ 0.24 MeV in excitation energy. The resulting cross sections are found to be far below previously published theoretical predictions.
