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