An experiment has been set up at the Institut Laue-Langevin in Grenoble to search for free neutron-antineutron oscillations. No candidate events were observed in the first run of the experiment, providing a lower limit in the oscillation time T.~ > 107 s at 90% CL, which improves the previous experimental limit by an order of magnitude.
