We study the ^99Be ground-state energy with non-local \alpha nαn and \alpha \alphaαα potentials derived from Cluster Effective Field Theory. The short-distance dependence of the interaction is regulated with a momentum cutoff. The potential parame

It is aimed to describe the nucleus of \(^9\)Be in an \(\alpha \)-\(\alpha \)-neutron cluster model, where the \(\alpha \)-\(\alpha \) and \(\alpha \)-neutron interactions are determined via an effective field theory (EFT) for halo nuclei (halo-EFT).

In view of the growing interest in neutrino scattering with nuclei we show that it is possible to extend to relatively high energies and momentum transfers the accurate ab initio results obtained by the integral transform (IT) approach for quasi-elas

We introduce a few extensions to the Hyperspherical Harmonics (HH) approach in order to include intrinsic excitations degrees of freedom. To this end we adapt the HH expansion method, usually built up starting from a fixed mass-weighted set of Jacobi

The electromagnetic responses obtained from Green's function Monte Carlo (GFMC) calculations are based on realistic treatments of nuclear interactions and currents. The main limitations of this method comes from its nonrelativistic nature and its com

Some general remarks about integral transform approaches to response functions are made. Their advantage for calculating cross sections at energies in the continuum is stressed. In particular we discuss the class of kernels that allow calculations of

These lecture notes intend to give a brief overview of some ab initio approaches currently used to study nuclear structure properties and reactions. In the first part particular attention is devoted to two methods useful to account for bound state pr

The Schrodinger equation is solved for an A-nucleon system using an expansion of the wave function in nonsymmetrized hyperspherical harmonics. Our approach is based on the formalism developed by Gattobigio et al. (Phys Rev A 79:032513, 2009; Few-Body

The electric dipole polarizability quantifies the low-energy behaviour of the dipole strength and is related to critical observables such as the radii of the proton and neutron distributions. Its computation is challenging because most of the dipole

What is the size of the atomic nucleus? This deceivably simple question is difficult to answer. Although the electric charge distributions in atomic nuclei were measured accurately already half a century ago, our knowledge of the distribution of neut
