The mean multiplicity and the angular distribution of the charged pions produced in the n̄ annihilation on Fe in the range from 12 to 140 MeV is presented. The experimental technique and methods of analysis are described. A comparison with the p̄ results is performed, together with a discussion of some possible pion-nucleus interaction mechanisms in the above n̄ energy range.

Abstract
The mean multiplicity and the angular distribution of the charged pions produced in the n̄ annihilation on Fe in the range from 12 to 140 MeV is presented. The experimental technique and methods of analysis are described. A comparison with the p̄ results is performed, together with a discussion of some possible pion-nucleus interaction mechanisms in the above n̄ energy range.
