Abstract
The production of backward pions in lepton-nucleus
collisions is analyzed. We show that
a large yield of high momentum backward pions
can be explained by the Regge asymptotic of
the distribution of nucleons carrying a large momentum fraction
in the nuclear target. The calculated spectra of pions emitted in the
and
reactions are in
satisfactory agreement with the available experimental data.
