The data recorded by the ALEPH experiment at LEP at centre-of-mass energies of 161 GeV and 172 GeV were analysed to search for sleptons, the supersymmetric partners of leptons. No evidence for the production of these particles was found. The number of candidates observed is consistent with the background expected from four-fermion processes and gamma gamma-interactions. Improved mass limits at 95% C.L. are reported. (C) 1997 Published by Elsevier Science B.V.
