  Bosons in the lowest Landau level, such as rapidly-rotating cold trapped
atoms, are investigated numerically in the specially interesting case in which
the filling factor (ratio of particle number to vortex number) is 3/2. When a
moderate amount of a longer-range (e.g. dipolar) interaction is included, we
find clear evidence that the ground state is in a phase constructed earlier by
two of us, in which excitations possess non-Abelian statistics.
