  A Kohn-Sham density functional approach has recently been developed for the
fractional quantum Hall effect, which maps the strongly interacting electrons
into a system of weakly interacting composite fermions subject to an exchange
correlation potential as well as a density dependent gauge field that mimics
the "flux quanta" bound to composite fermions. To get a feel for the role of
various terms, we study the behavior of the self-consistent solution as a
function of the strength of the exchange correlation potential, which is varied
through an {\it ad hoc} multiplicative factor. We find that a crystal phase is
stabilized when the exchange correlation interaction is sufficiently strong
relative to the composite-fermion cyclotron energy. Various properties of this
crystal are examined.
