  An application of the general equation obtained in Part I to low critical
temperature superconductors utilizing an "ad hoc" phononic theory is developed.
Then, we arrive to a specific expression for the bounding energy as a function
of temperature. The density of states of the electron pairs is calculated and
used to obtain an equation for the critical magnetic field. This result is
needed for determine the electrodynamical properties. Finally, we obtain the
specific heat as a function of temperature and compare it to experimental data
for Sn, and calculate its jump at Tc for eight superconductors.
