We have tested Haldane's ``fractional-Pauli-principle'' description of
excitations around the ν=1/3 state in the FQHE, using exact results for
small systems of electrons. We find that Haldane's prediction β=±1/m
for quasiholes and quasiparticles, respectively, describes our results well
with the modification βqp=2−1/3 rather than −1/3. We also find
that this approach enables us to better understand the {\it energetics\/} of
the ``daughter'' states; in particular, we find good evidence, in terms of the
effective interaction between quasiparticles, that the states ν=4/11 and
4/13 should not be stable.Comment: 9 pages, 3 Postscript figures, RevTex 3.0. (UCF-CM-93-005
