Two-Particle-Two-Hole Jπ=0+ States of 40Ca
— Interplay between Particle-Particle (Hole-Hole) Correlations and Particle-Hole Correlations

The correlated two-particle-two-hole states with Jπ=0+ of 40Ca are described in terms of the two-particle-two-hole excitation modes in the framework of the new Tamm-Dancoff method. The agreement between the calculated and the observed energy spectra of these states is considerably good. The interplay between the particle-particle (hole-hole) correlations and the particle-hole ones is investigated through the structure of these states. It is concluded that the particle-hoel interaction mixes multipole particle-particle (hole-hole) correlations but does not spoil the “collective” structure of each multipole particle-particle (hole-hole) correlation. It may be possible to describe the low-lying two-particle-two-hole states with Jπ=0+ in terms of only collective two-particle and two-hole modes.
