We study both the static properties of 11 Be and its reaction dynamics during electromagnetic breakup under a unified framework. A many-body approach -the antisymmetrized molecular dynamics (AMD) is used to describe the structure of the neutron-halo nucleus, 11 Be. The same AMD wave function is then adapted as an input to the fully quantum theory of Coulomb breakup under the aegis of the finite range distorted wave Born approximation theory. The calculated observables are also compared with those obtained with a phenomenological Woods-Saxon potential model wave function. The experimental core-valence neutron relative energy spectrum and dipole response along with other observables are well described by our calculations.

“…This canonical coordinate transformation is known as the Talmi-Moshinsky transformation [70]. Secondly, we assume that the two protons are transferred one by one passing through the intermediate partition 19 F+ 39 K. This sequential two-proton transfer process was performed considering the CCBA. In this approach we couple excited states to the ground state to infinite order (coupled channels) in the initial and final partitions, and the couplings among the partitions to first order.…”

“…Therefore, one and two-neutron transfer reactions were extensively investigated, as reported in Refs. [8][9][10][11][12][13][14][15][16][17][18][19]. In those works, the comparison with theoretical results shows that the transfer mechanism depends also on the nuclear structure of the involved nuclei.…”

Two-nucleon transfer reactions are essential tools to investigate specific features of the nuclear structure such as the correlation among valence particles in the transfer process. Besides, transfer reactions may be an important channel to take into account in charge exchange processes since they can represent a competing contribution to the final cross section. The two-proton pickup transfer reaction 40 Ca( 18 O, 20 Ne) 38 Ar has been measured at 270 MeV and the angular distributions for transitions to different excited states extracted. This work shows the analysis of the data performed by finite-range coupled reaction channel and coupled channel Born approximation methods. Extensive shell-model calculations are performed to derive the one-and two-proton spectroscopic amplitudes for the projectile and target overlaps. The role of the simultaneous and sequential two-proton transfer mechanisms to populate the measured final states or groups of states, mainly characterized by a high collectivity, is also discussed.

“…It should be noted that ab initio approaches focused on the discussed problem are already presented in the literature. Among them the methods which combine NCSM and Resonating Group Model (RGM) namely No-Core Shell Model / Resonating Group Model (NCSM/RGM) [28] and No-Core Shell Model with Continuum (NCSMC) [29][30][31][34][35][36][37] seem to be the most versatile. To describe resonances (including those undergoing multiparticle decay) using calculations of scattering phase shifts the NCSM-based SS-HORSE method was proposed [32,33].…”

The energies and decay widths of the states of the exotic 7 He nucleus are studied in an ab initio approach. The spectrum of these states is calculated using No-Core Shell Model and corresponding extrapolation procedure. Well-proven on a large amount of data the Daejeon16 potential is used in the calculations. The previously developed NCSM-based approach, which includes a method for constructing the basis of orthogonalized functions of cluster channels and a procedure for matching the cluster form factors obtained within this method with the corresponding asymptotic wave functions, is applied to compute the decay widths of the levels. The possibilities of the approach for calculating the partial decay widths of nuclear states into various channels strongly differing in type of fragmentation, spin, angular momentum of relative motion, and amplitude are demonstrated. The results obtained are compared with the results of other microscopic calculations.
