Pion-Nucleus Scattering in an Isobar-Doorway Model
Journal Article
·
· Physical Review Letters
Elastic pion-nucleus scattering is treated using a separation in Hilbert space via a projection-operator formalism. The basic assumption is that the elastic scattering and reactions due to the pi -N resonance proceed through doorway states consisting of a DELTA (1236) resonance in the nucleus. Nonresonant scattering and absorption processes are included by background term, which are approximately known. The formlism is applied to pi /sup -/-/sup 12/C scattering. (auth)
