Abstract

The intensities of $γ$ rays from $π^{-}$ absorption at rest on O, F, Mg, P, Ca, and Nb have been measured. The results are compared with those at 220 MeV, previously published. The $α$ removal processes which have been reported to dominate at higher energies are not as pronounced in the present work.
