Optimizing artificial neural networks for dipole strength predictions in light nuclei
Tim Egert, Weiguang Jiang, Sonia Bacca
We present an optimized artificial neural network approach for predicting electric dipole strength functions in nuclei with . Building upon a previous global study [Phys.Re…
Nuclear Charge Radius of Be from Muonic Atom Spectroscopy Using a Microcalorimeter
Ofir Eizenberg, Shikha Rathi, Andreas Abeln +34
The transition energy in muonic Be was measured using a metallic magnetic calorimeter, resulting in eV. The result is 30 times more pre…
From closed shells to open shells: Coupled-cluster calculations of atomic nuclei
F. Marino, F. Bonaiti, P. Demol +6
Coupled-cluster theory is a powerful tool for first-principles calculations of atomic nuclei, enabling accurate predictions of nuclear observables across the Segrè chart. While cou…
Ab initio calculations of monopole sum rules: From finite nuclei to infinite nuclear matter
Francesca Bonaiti, Andrea Porro, Sonia Bacca +2
We compute moments of the isoscalar monopole response of N = Z closed-shell nuclei based on chiral nucleon-nucleon plus three-nucleon interactions. We employ the random phase appro…
Electromagnetic sum rules for 22O from coupled-cluster theory
Francesco Marino, Miriam El Batchy, Sonia Bacca
In this contribution, we discuss recent results on the determination of the electric dipole polarizability for the neutron-rich isotope O within the ab initio framewor…
Bridging reaction theory and nuclear structure in -Ca scattering
Viacheslav Tsaran, Francesco Marino, Sonia Bacca +2
We extend the pion-nucleus multiple-scattering framework to include detailed second-order rescattering dynamics for nuclei with non-zero isospin. To account for intermediate charge…
Structure and dynamics of open-shell nuclei from spherical coupled-cluster theory
Francesco Marino, Francesca Bonaiti, Sonia Bacca +2
We extend the spherical coupled-cluster ab initio method for open-shell nuclei where two nucleons are removed from a shell subclosure. Following the recent implementation of the tw…
Data-driven analysis of dipole strength functions using artificial neural networks
Weiguang Jiang, Tim Egert, Sonia Bacca +2
We present a data-driven analysis of dipole strength functions across the nuclear chart, employing an artificial neural network to model and predict nuclear dipole responses. We tr…

The electric dipole strength distribution in Ni between 6 and 20 MeV has been determined from proton inelastic scattering experiments at very forward angles at RCNP, Osaka.…
Electromagnetic observables of open-shell nuclei from coupled-cluster theory
Francesca Bonaiti, Sonia Bacca, Gaute Hagen +1
We develop a new method to describe electromagnetic observables of open-shell nuclei with two nucleons outside a closed shell. This approach combines the equation-of-motion coupled…
