Large Scale Shell Model Calculations of the Negative-Parity States Structure in 24Mg Nucleus

The negative-parity states of 24Mg nucleus are investigated within the shell model. We are based on the calculations of energy levels, total squared form factors, and transition probability using the p-sd-pf (PSDPF) Hamiltonian in a large model space (0 + 1) hW. The comparison between the experimental and theoretical states showed a good agreement within a truncated model space. The PSDPF-based calculations successfully reproduced the data on the total squared form factors and transition probabilities of the negative-parity states in 24Mg nucleus. These quantities depend on the one-body density matrix elements that are obtained from the PSDPF Hamiltonian. The wave functions of radial one-particle matrix elements calculated with the harmonic-oscillator potential are suitable to predict experimental data by changing the center-of-mass corrections.

“…RAHIM, 2020 many features of nuclear energy levels. The importance of the nuclear shell model lies in its ability to give a true accurate approximation of the energy levels of nucleons with different values of angular momentum [2,3]. The shell model had been modified significantly to involve large neutron systems, which is very necessary in the field of astronomy and has many applications in the study of the great explosions called supernova and other fields [4].…”

The energy levels and transition probabilities B(E2; ↓) i B(M1; ↓) have been investigated for 21,23Na isotopes by using the (USDA and USDB) interactions in the (sd-shell) model space. In the calculations of the shell model, it has been assumed that all possible many-nucleon configurations are specified by the (0d5/2, 1s1/2 i 0d3/2) states above 16O doubly magic nucleus. The available empirical data are in a good agreement with predictions of theoretical energy levels. Spins and parities are affirmed for new levels, transition probabilities B(E2; ↓) and B(M1; ↓) are predicted as well.

The Coulomb form factors for the elastic and inelastic electron-nucleus scatterings have been calculated for 12C and 20Ne nuclei in the ground and excited states with the same parity. We use a microscopic theory involving the effects from high configurations outside the model space, which are called the Core Polarization (CP) effects. For the core polarization matrix elements, the realistic Michigan sum of the three-range Yukawa (M3Y) interaction and the Modified Surface Delta Interaction (MSDI) are used as the two-body interactions. Additionally, the Harmonic Oscillators (HO) potential is applied to calculate wave functions. In the final step, a comparison has been made between the theoretical calculations of Coulomb form factors based on (M3Y) and (MSDI) interactions and the available experimental data. It is noticed that the Coulomb form factors for the (M3Y) interaction give a sensible delineation of the measured data.
