Abstract

The experimental search for neutron-antineutron oscillations has been completed at the ILL high flux reactor at Grenoble. A neutron beam of intensity 1011n s−1 was propagated for a timet≅0.1 s in vacuum in a region shielded against the external magnetic field. No antineutron was detected in 2.4·107 s running time. The lower limit\(\tau _{n\bar n} \mathbin{\lower.3ex\hbox{$\buildrel>\over{\smash{\scriptstyle=}\vphantom{_x}}$}} 0.86 \cdot 10^8 \) s for\(n\bar n\) transitions was established at 90% C.L.
