Background: The variational multiparticle-multihole configuration mixing approach to nuclei has been proposed about a decade ago. While the first applications followed rapidly, the implementation of the full formalism of this method has only been recently completed and applied in Ref.[1] to 12 C as a test-case.Purpose: The main objective of the present paper is to carry on the study that was initiated in that reference, in order to put the variational multiparticle-multihole configuration mixing method to more stringent tests. To that aim we perform a systematic study of even-even sd-shell nuclei.Method: The wave function of these nuclei is taken as a configuration mixing built on orbitals of the sd-shell, and both the mixing coefficients of the nuclear state and the single-particle wave functions are determined consistently from the same variational principle. As in the previous works, the calculations are done using the D1S Gogny force.Results: Various ground-state properties are analyzed. In particular, the correlation content and composition of the wave function as well as the single-particle orbitals and energies are examined. Binding energies and charge radii are also calculated and compared to experiment. The description of the first excited state is also examined and the corresponding transition densities are used as input for the calculation of reaction processes such as inelastic electron and proton scattering. Special attention is paid to the effect of the optimization of the single-particle states consistently with the correlations of the system. Conclusions:The variational multiparticle-multihole configuration mixing approach is systematically applied to the description of even-even sd-shell nuclei. Globally, the results are satisfying and encouraging. In particular, charge radii and excitation energies are nicely reproduced. However, the chosen valence-space truncation scheme precludes achieving maximum collectivity in the studied nuclei. Further refinement of the method and a bettersuited interaction are necessary to remedy this situation.

The fit to the experimental data in the present MCC calculation is superior to the previous coupled-channel calculations that were based on the phenomenological treatment in the coupling potential [10][11][12].

“…Nucleon scattering from carbon is very important in the fields of nuclear engineering [8] and medical technology [9]. There are several coupled-channel (CC) calculations of the p + 12 C inelastic scattering at the energy of E p ≤ 65 MeV [10][11][12]. However, in these CC calculations, the nuclear potentials are treated in a phenomenological manner, and there is no approach of the full microscopic coupled-channels calculation, in which the nuclear interactions are calculated from a microscopic wave function of 12 C based on the nucleon degrees of freedom and a reliable nucleon-nucleon (NN) interaction.…”

Abstract. The microscopic coupled-channel (MCC) calculations for proton + 12 C inelastic scattering are performed in the energy range of E p = 29.95 MeV to 65 MeV. The nuclear interactions for the proton − 12 C system are constructed from the folding model, which employs the internal wave function of 12 C, obtained from the 3α resonating group method (3α RGM), and an effective nucleon-nucleon interaction of the density-dependent Michigan three-range Yukawa (DDM3Y). The MCC calculation with the 3α RGM + DDM3Y nicely reproduces all of the differential cross sections for elastic and inelastic scattering in the angular range of θ c.m. = 30 • to 120 • . We introduce a scattering radius, which characterizes a spatial size of the scattering area, from partial wave decompositions of an angle-integrated cross section. The scattering radii for the elastic scattering and the various inelastic channels, which involve the rotational or vibrational excitations and the 3α excitations in 12 C, are derived. We found that the scattering radii for the inelastic channels with a well developed 3α structure are strongly enhanced in comparison to the scattering radii for the elastic and collective channels. This enhancement of the scattering radius for the 3α channel strongly suggests that the scattering radius is sensitive to a size of the intrinsic structure of the finally excited state in the scattering process.

A consistent analysis for nuclear level structure and nucleon scattering data up to 200 MeV was performed for sd-shell nuclei, 28,30 Si, using a unified framework of soft-rotator model and coupled-channels approach. The 28,30 Si were assumed to be deformed nuclei having oblate shapes. The soft-rotator model parameters were determined so as to reproduce measured collective levels of 28,30 Si up to an excitation energy of around 10 MeV. The relativistic kinematics and global optical potential form were taken into account in the coupled-channels optical model analysis, and the optical model parameters were derived. The calculation showed good agreement with experimental data for both collective levels and nucleon interaction data-neutron total cross sections, proton reaction cross sections, and nucleon scattering angular distributions.
