Abstract

We present some remarks on the \(\bar n\) p partial branching ratios in flight at low momenta of antineutrons measured by the OBELIX Collaboration. A comparison is made to the known branching ratios from the p \(\bar p\)-atomic states. The branching ratio for the reaction \(\bar n\) p → π+π0 is found to be suppressed in comparison to what follows from the p \(\bar p\) data. It is also shown that there is no so-called dynamical I=0 amplitude suppression for the process N \(\bar N\) → K \(\bar K\).
