Abstract

The nuclear equation of state and incompressibility are studied in a model with correlations. We first consider a Hartree solution and then add one-particle-one-hole (1p-1h) and two-particle-two-hole (2p-2h) admixtures into the wave function using a separable monopole-monopole interaction λr2(i)r2(j) which induces giant monopole vibrations. Stable and unstable points arise in the nuclear equation of state as a function of the oscillator size parameter from pure 1p-1h admixtures. Addition of 2p-2h admixtures leads to one stable point. However, the incompressibility is found to be quite different from the Hartree case with 1p-1h admixtures, even with 2p-2h states included.
