“…This effect decreases when the model-space size increases as is demonstrated in our earlier threenucleon shell-model calculations [25]. Several possible adjustments have been discussed to deal with this problem [4,9] in smaller model spaces and amount to introducing an extra parameter. In the present calculations, we use two methods introduced in the previous papers.…”

“…With regard to the 4hΩ calculation for the 0p-shell nuclei, the choice of N max = 6 appears to be appropriate. However, it has been observed in the past [4,7,9] that when the Lee-Suzuki procedure is combined with the G-matrix calculation according to Ref. [23] (which is equivalent to the procedure we are using) and is applied to calculate the two-body effective interaction, the resulting interaction may be too strong.…”

Results of large-basis shell-model calculations for nuclei with A = 7 − 11 are presented. The effective interactions used in the study were derived microscopically from the Reid93 potential and take into account the Coulomb potential as well as the charge dependence of T = 1 partial waves. For A = 7, a 6hΩ model space was used, while for the rest of the studied nuclides, the calculations were performed in a 4hΩ model space. It is demonstrated that the shell model combined with microscopic effective interactions derived from modern nucleon-nucleon potentials is capable of providing good agreement with the experimental properties of the ground state as well as with those of the low-lying excited states.

Large-space no-core shell model calculations have been performed for 3 H, 4 He, 5 He, 6 Li, and 6 He, using a starting-energy-independent two-body effective interaction derived by application of the Lee-Suzuki similarity transformation. This transformation can be performed by direct calculation or by different iteration procedures, which are described. A possible way of reducing the auxiliary potential influence on the two-body effective interaction has also been introduced. The many-body effects have been partially taken into account by employing the recently introduced multi-valued effective interaction approach. Dependence of the 5 He energy levels on the harmonic-oscillator frequency as well as on the size of the model space has been studied. The Reid 93 nucleon-nucleon potential has been used in the study, but results have also been obtained using the Nijmegen II potential for comparison.

Within the framework of the radially constrained spherical Hartree-Fock (CSHF) approximation, the resonance effects of delta on the properties of neutron-rich double magic spherical nucleus 132 Sn were studied. It was found that most of the increase in the nuclear energy generated under compression was used to create massive particles. For 132 Sn nucleus under compression at 3.19 times density of the normal nuclear density, the excited nucleons to s were increased sharply up to 16% of the total number of constituents. This result is consistent with the values extracted from relativistic heavy-ion collisions. The single particle energy levels were calculated and their behaviours under compression were examined. A meaningful agreement was obtained between the results with effective Hamiltonian and that with the phenomenological shell model for the low-lying single-particle spectra. The results suggest considerable reduction in compressibility for the nucleus, and softening of the equation of state with the inclusion of s in the nuclear dynamics.
