Abstract

Angular distributions of neutrons from the ²⁰⁸Pb( pi ^+or-, pi ^+or-'n) reaction near the giant-resonance region have been measured at T_pi=180 MeV. The neutrons arising from pi ^- inelastic scattering show evidence of peaking near the quasi-free recoil direction in contrast to those arising from pi ⁺. This observation may be explained by a direct neutron-decay width for the giant resonances that is large when they are excited in ( pi ^-, pi ^-') and small in ( pi ⁺, pi ^+'). Consequences of this suggestion for the analysis of inelastic scattering to the continuum are examined.
