Query: Effective nucleon-nucleon interactions and nuclear matter equation of
  state   Nuclear matter equations of state based on Skyrme, Myers-Swiatecki and
Tondeur interactions are written as polynomials of the cubic root of density,
with coefficients that are functions of the relative neutron excess $\delta$.
In the extrapolation toward states far away from the standard one, it is shown
that the asymmetry dependence of the critical point ($\rho_c, \delta_c$)
depends on the model used. However, when the equations of state are fitted to
the same standard state, the value of $\delta_c$ is almost the same in Skyrme
and in Myers-Swiatecki interactions, while is much lower in Tondeur
interaction. Furthermore, $\delta_c$ does not depend sensitively on the choice
of the parameter $\gamma$ in Skyrme interaction.
