We consider the spinless fermion model with hard-core repulsive
potential between particles extended on a few lattice sites
. The Luttinger-liquid behavior is studied for
different values of a hard-core radius. We derive a critical
exponent 
of the one-particle correlation function
for an arbitrary electron
density and coupling constant. Our results show that at high
density the behavior of fermions can be described as a strongly
interacting Luttinger liquid with 
. As a result, the
residual Fermi surface disappears.
