Abstract

The fragmentation of deuterons into pions emitted forward in the kinematic region forbidden for free nucleon-nucleon collisions is analyzed. It is shown that the inclusion of the non-nucleon degrees of freedom in a deuteron allows to describe the experimental data about inclusive pion spectrum rather satisfactory and improves the description of data concerning the deuteron analyzing power T₂₀. The experimental data show the positive sign and very small values, less than 0.2, of T₂₀ what can't be reproduced by the calculations ignoring these degrees of freedom.
