  We have studied the effect of free space nucleon radius on the nuclear matter
and slowly rotating neutron star properties within a relativistic mean field
model with the inclusion of omega-rho mixing nonlinear term. We use the same
density dependent radius as in our previous work. However, in the present work
we utilize the parameter sets with more proper symmetric nuclear matter (SNM)
predictions for a number of different nucleon radii. To this end, the isoscalar
parameters in each parameter set and the cutoff parameter $\beta$ are adjusted
by fitting the corresponding SNM properties at sub-saturation density to the
prediction of IUFSU parameter set. We have obtained that the assumption of
composite nucleons with free space radius $r \le 0.83$ fm is still compatible
with the currently acceptable nuclear matter (NM) properties beyond the
saturation density. We have also found that the effect of free space nucleon
radius could be imprinted in the radius, moment of inertia, and crust
properties of the slowly rotating neutron star.
