Abstract

The angular correlation of the ( $π^{+}$ ,pp) and ( $π^{-}$ ,pp) cross sections for ${}^{6}{Li}$ , ${}^{7}{Li}$ , and C was measured in a wide angular range. We analyzed the structure of the ( $π^{+}$ ,pp) angular correlation comparing cross sections between the two reactions. It was found that the broad component of the ( $π^{+}$ ,pp) angular correlation is mainly due to the two-step processes associated with the two-nucleon absorption.
