Regrowth of ion-damaged YBa{sub 2}Cu{sub 3}O{sub 7{minus}}{sub {delta}} thin films on LaAlO{sub 3} was studied using the ion beam channeling technique. The damaged films can be regrown at a temperature as low as 650 {degree}C, and are stable up to 1000 {degree}C. The regrowth process was found to be thermally activated with a single activation energy of 0.46 eV, contrary to two energies found in a previous study on the films on MgO (J. A. Martinez {ital et} {ital al}., Appl. Phys. Lett. {bold 57}, 189 (1990)).
