Compressibility and equation of state of finite nuclei

We present a new approach for calculating the nuclear equation of state and compressibility for finite nuclei using the density-constrained Hartree-Fock method.

Figure 1

Scaled density obtained for the ${}^{48}\mathrm{Ca}$ nucleus for various values of the scaling parameter $s$. The inset shows the same quantity on a logarithmic scale. The force used was SLy4 without the Coulomb contribution.

Figure 2

EOS for the ${}^{40}\mathrm{Ca}$, ${}^{48}\mathrm{Ca}$, and ${}^{60}\mathrm{Ca}$ nuclei as a function of density. Please see the comments in the manuscript regarding the density values. The force used was SLy4 without the Coulomb contribution.

Figure 3

The quantity $S(\rho )$ for the ${}^{48}\mathrm{Ca}$ and ${}^{60}\mathrm{Ca}$ nuclei as a function of density.
