Searches for supersymmetric particles produced in e(+)e(-) collisions at centre-of-mass energies of 130 and 136 GeV have been performed in a data sample of 5.7 pb(-1) collected in the autumn of 1995 by the ALEPH detector at LEP. No candidate events were found, allowing limits to be set on the masses and production cross-sections of scalar leptons, scalar tops, charginos and neutralinos. The domains previously excluded at LEP1 are substantially extended. For instance, masses of gaugino-like charginos smaller than 67.8 GeV/c(2) are excluded at the 95% C.L. for scalar neutrino masses larger than 200 GeV/c(2).

Abstract
Searches for supersymmetric particles produced in e(+)e(-) collisions at centre-of-mass energies of 130 and 136 GeV have been performed in a data sample of 5.7 pb(-1) collected in the autumn of 1995 by the ALEPH detector at LEP. No candidate events were found, allowing limits to be set on the masses and production cross-sections of scalar leptons, scalar tops, charginos and neutralinos. The domains previously excluded at LEP1 are substantially extended. For instance, masses of gaugino-like charginos smaller than 67.8 GeV/c(2) are excluded at the 95% C.L. for scalar neutrino masses larger than 200 GeV/c(2).
