Summary

Antineutrons have been produced by the charge exchange of antiprotons in an emulsion stack and their annihilations observed in the same stack. The cross-section for production is estimated to be (17±6) mb for antiprotons at a mean energy of 125 MeV. The mean multiplicity, the mean energy of the secondary mesons, and the star sizes of the annihilations of antineutrons, are very similar to those for antiprotons.

Riassunto

Si sono prodotti antineutroni con lo scambio di carica degli antiprotoni in un pacco di emulsioni e nello stesso pacco si sono osservate le loro annichilazioni. Si valuta che la sezione d’urto per la produzione sia di (17±6) mb per antiprotoni di una energia media di 125 MeV. La molteplicità media, l’energia media dei mesoni secondari e le dimensioni delle stelle delle annichilazioni degli antineutroni sono molto simili a quelle degli antiprotoni.
