Three-pion production on complex nuclei at 23 GeV/ c

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

Beschreibung
Zusammenfassung:	The production of three pions has been examined in interactions of 23-GeV/c ..pi../sup -/ 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/sub 1/ region the absorption cross sections obtained from the model are 25 mb for J/sup P/ = 1/sup +/ and 60 mb for J/sup P/ = 0/sup -/.
