Until now latent tracks have never been observed by transmission electron microscopy in metallic targets. For the first time we observe discontinuous tracks in a crystalline nickel-zirconium ordered alloy irradiated at 80 K by 3 GeV uranium ions. The diameter of the tracks is of about 3 nm and their number is close to the number of incoming ions. This result is due to the very high value of the electronic stopping power of the target for uranium ions and probably to specific properties of the compound.
