  Results are presented of a Monte Carlo simulation of a 2+1 dimensional
Gross-Neveu model with SU(2)xSU(2) chiral symmetry at non-zero baryon chemical
potential, corresponding to non-zero baryon density. The phenomenon of quark
pair condensation is sought via measurement of a two point function. For
sufficiently large chemical potential there is a sharp transition between a
phase where the chiral symmetry is broken by a standard chiral condensate and
one where a scalar diquark condensate, qq, is non-zero. Global U(1) baryon
number symmetry may remain unbroken, however, due to the absence of long range
order in the phase of qq.
