Test of isospin symmetry via low energy ${}^1$H(${\pi }^{-}$,${\pi }^o$)$n$ charge exchange

Y. Jia, T. P. Gorringe, M. D. Hasinoff +5

We report measurements of the ${\pi }^{-}p\to {\pi }^{o}n$ differential cross sections at six momenta (104-143 MeV/c) and four angles (0-40 deg) by detection of $\gamma$-ray pairs from $π^o \to γγ…
