Abstract
Small violations of the baryon number conservation law are predicted by the Grand Unified Theories. Several attempts have been made to observe a ΔB = 1 violation in proton decay experiments. The negative result of these searches can also be interpreted to give a lower limit in the range 107 ÷108 sec to the characteristic time of the ΔB = 2 process of n — n oscillations. But this limit rests on nuclear model assumptions. Only one experiment has been carried out so far to search directly for free neutron-antineutron oscillations, using cold neutrons from the ILL Grenoble reactor [1].
