  We consider the finkelstein action describing a system of spin polarized or
spinless electrons near two dimensions, in the presence of disorder as well as
the Coulomb interactions.We extend the renormalization group analysis of our
previous work and evaluate the metal-insulator transition of the electron gas
to second order in an (d-2) expansion. We obtain the complete scaling behavior
of physical observables like the conductivity and the specific heat with
varying frequency, temperature and/or electron density.
