摘要：

The experimental search for neutron-antineutron oscillations has been completed at the ILL high flux reactor at Grenoble. A neutron beam of intensity 10(11) n s-1 was propagated for a time t congruent-to 0.1 s in vacuum in a region shielded against the external magnetic field. No antineutron was detected in 2.4.10(7) s running time. The lower limit tau(nnBAR) greater-than-or-equal-to 0.86.10(8) s for nnBAR transitions was established at 90% C.L.
