“…As the neutron number increases from 8 to 20 and from 20 to 34, the shape of nucleus goes from spherical to prolate, and then back to spherical. The ground state of 24 Mg is well deformed with the largest quadrupole deformation β 2 ≈ 0.60, which is consistent with the experimental value β 2 = 0.609(6) [65]. By comparing (a) and (b), one can find the appearance of the bump near 24 Mg is caused by the strong deformation effect.…”

Particles in the classically forbidden areas are studied based on the deformed relativistic Hartree-Bogoliubov theory in continuum with PC-PK1 for magnesium isotopes. It is shown the deformation effect makes the number of particles in the classically forbidden areas increase. By analyzing the neutron and proton radii, it is found that the largest deviations from the empirical values appear at the predicted neutron halo nuclei 42 Mg and 44 Mg. Consistently, a notable increase at 42 Mg and 44 Mg is found in the total number of neutrons in the classically forbidden areas that includes the number of neutrons in continuum.

“…The rotational spectra 20 Ne and 24 Mg are reproduced in our ab initio calculations. The E 2 + 1 and B(E2; 2 + 1 → 0 + 1 ) transitions using ab initio interactions and USDB interactions along with experimental data [16,17] To see the importance of neutron excitations from sd to pf shell, we have shown results with 2p − 2h and 4p − 4h excitations in Fig. 3.…”

In the present work, we have reported shell model results for open shell nuclei Ne, Mg and Si isotopes with 10 ≤ N ≤ 20 in sd-shell model space. We have performed calculations in sd shell with two ab initio approaches: in-medium similarity renormalization group (IM-SRG) and coupledcluster (CC) theory. We have also performed calculations with phenomenological USDB interaction and chiral effective field theory based CEFT interaction. The results for rotational spectra and B(E2; 2 + 1 → 0 + 1 ) transitions are reported for even-mass isotopes. The IM-SRG and CC results are in reasonable agreement with the experimental data except at N =20. This demonstrates a validity of ab initio description of deformation for doubly open-shell nuclei for sd shell. To see the importance of pf orbitals, we have also compared our results with SDPF-MU interaction by taking account of 2p − 2h and 4p − 4h configurations in sd-pf -shell model space.

“…Since both g.s. quadrupole moments of projectile and target are large [43], one has to infer that 20 Ne and 76 Ge isotopes are significantly deformed. Moreover at these transferred momenta the hypothesis of frozen nuclear spherical matter in the reaction mechanism is at limit.…”

Background: Double Charge Exchange (DCE) nuclear reactions have recently attracted much interest as tools to provide experimentally driven information about the Nuclear Matrix Elements of interest in the context of neutrino-less double beta decay. In this framework a good description of the reaction mechanism and a complete knowledge of the initial and final state interactions is mandatory. Presently, not enough is known about the details of the optical potentials and nuclear response to isospin operators for many of the projectile-target systems proposed for future DCE studies. Among these, 20 Ne + 76 Ge DCE reaction is particularly relevant due to its connection with 76 Ge double beta decay. Purpose: Characterization of the initial state interaction for the 20 Ne + 76 Ge reactions at 306 MeV bombarding energy: determination of the optical potential and exploration of the role of the couplings between elastic channel and inelastic transitions to the first low-lying excited states. Methods: Determination of the experimental elastic and inelastic scattering cross section angular distributions. Comparison of the theoretical predictions adopting different models of optical potentials with the experimental data. Evaluation of the coupling effect through the comparison of the Distorted Wave Born Approximation calculations with the Coupled Channels ones. Results: Optical Models fail in the description of the elastic angular distribution above the grazing angle (∼ 9.4 • ). A correction in the geometry to effectively account for deformation of the involved nuclear systems improves the agreement up to about 14 • . Coupled channels effects are crucial to obtain a good agreement at large angles in the elastic scattering cross section. Conclusions: The analysis of elastic and inelastic scattering data turned out to be a powerful tool to explore the initial and final state interaction in heavy ion nuclear reactions also at high transferred momenta. * Electronic address: alessandro.spatafora@lns.infn.it † Electronic address: cappuzzello@lns.infn.it
