We show that the quantum uncertainty principle puts
some limits on the effectiveness of the antinucleon-nucleus
annihilation at very low energies. This is caused by the fact
that a very effective short-distance reaction
process implies information on the relative distance of the
reacting particles. Some quantitative predictions are possible
on this ground, including the approximate A-independence of
-nucleus annihilation rates.
