The energies and matter densities of finite nuclei under radial compression are predicted by using a constrained Hartree-Fock method with the degree of freedom included. The results are presented for Zr in a calculation within a model space of seven major oscillator shells. The main feature of this calculation is that the effective baryon-baryon interactions associated with the are evaluated within a -matrix approach based on a coupled-channel model that can describe the data up to 1 GeV. It is found that as the nucleus is compressed to about 2–3 times of the ordinary nuclear density, the component is sharply increased to about 10% of all baryons in the system. This result is consistent with the values extracted from relativistic heavy-ion collisions.
