Searches for pair-production of supersymmetric particles under the assumption that R-parity is violated via a single dominant LL (E) over bar, LQ (D) over bar, or (U) over bar (D) over bar (D) over bar coupling are performed using the data collected by the ALEPH collaboration at centre-of-mass energies of 181-184 GeV. The observed candidate events in the data are in agreement with the Standard Model expectations. Upper limits on the production cross-sections and lower limits on the masses of charginos, sleptons, squarks and sneutrinos are derived.
