Properties of Inclusive (π+, π0) Reactions in Nuclei

Abstract

Nuclear pion single charge exchange has been studied using a method of ${\ensuremath{\pi}}^{0}$ detection based on the spectroscopy of the band-angle decay $\ensuremath{\gamma}$ ray. For incident 100-MeV positive pions, charge-exchange scattering from nuclei ranging from Be to Pb was studied. For all targets the ${\ensuremath{\pi}}^{0}$ spectra were broad, extending over the entire range 0-100 MeV. Data were taken at 40\ifmmode^\circ\else\textdegree\fi{} and 120\ifmmode^\circ\else\textdegree\fi{} and in all cases the data show a backward peaking. The yields vary about as ${A}^{\frac{2}{3}}$.
