Abstract

The production of three pions has been examined in interactions of 23-GeV/c

π^{-}

with complex nuclei. A partial-wave analysis of the three-pion system has been performed showing that the spin-parity structure is very similar to the one produced in hydrogen. The production cross section for various nuclei have been compared with an optical-model calculation. In the

A_{1}

region the absorption cross sections obtained from the model are 25 mb for

J^{P} = 1^{+} and 60

mb for

J^{P} = 0^{-}
