INTERMEDIATE BASE-LINE APPEARANCE EXPERIMENTS AND 3-NEUTRINO MIXING SCHEMES

Three-neutrino mixing schemes suggested-by Cardall & Fuller and Acker & Pakvasa are compared and contrasted. Both of these schemes seek to s olve the solar and atmospheric neutrino problems and to account for th e possible neutrino oscillation signal in the LSND experiment. These n eutrino oscillation schemes have different atmospheric and solar neutr ino signatures that will be discriminated by Super-Kamiokande and SNO. They will also have different signatures in proposed long-baseline ac celerator and reactor experiments. In particular, both of these scheme s would give dramatic (and dramatically different) signals in an ''int ermediate baseline'' experiment, such as the proposed ICARUS detector in the Jura mountains 17 km from CERN.
