Modelling the cosmological Lyman–Werner background radiation field in the early Universe
(Oxford University Press, 2023)
The Lyman–Werner (LW) radiation field is a key ingredient in the chemothermal evolution of gas in the early Universe, as it dissociates H2 molecules, the primary cooling channel in an environment devoid of metals and dust. ...

A segmented total energy detector (sTED) for (n, gamma) cross section measurements at n_TOF EAR2
(EPJ Web of Conf., 2023)
The neutron time-of-flight facility n_TOF is characterised by its high instantaneous neutron intensity, high resolution and broad neutron energy spectra, specially conceived for neutron-induced reaction cross section ...

Multiple Mechanisms in Proton-Induced Nucleon Removal at ∼100 MeV/Nucleon
(American Physical Society, 2023)
We report on the first proton-induced single proton- and neutron-removal reactions from the neutron-deficient O14 nucleus with large Fermi-surface asymmetry Sn-Sp=18.6 MeV at ∼100 MeV/nucleon, a widely used energy regime ...

Double charge-exchange reactions for the nuclear matrix elements of neutrinoless double beta decay
(Journal of Physics: Conference Series, 2023)
Double charge exchange (DCE) reactions induced by heavy ions are crucial tools to access information relevant for neutrinoless double beta decay nuclear matrix elements. In this context the NUMEN project aims to investigate, ...

Advances on clusters and correlations in nuclear structure and reactions
(Journal of Physics Conference Series, 2023)
Recent advances obtained in the last few years by the Theoretical Nuclear Physics group in Padova with various collaborators on alpha-cluster models and on nuclear correlations in stable and unstable light nuclei are ...

Neutron Capture Measurements with High Efficiency Detectors and the Pulse Height Weighting Technique
(Elsevier, 2023)
Neutron capture cross section measurements in time-of-flight facilities are usually performed by detecting the prompt γ-rays emitted in the capture reactions. One of the difficulties to be addressed in these measurements ...

Optimal Resetting Strategies for Search Processes in Heterogeneous Environments
(Institute of Physics Publishing, 2023)
In many physical situations, there appears the problem of reaching a single target that is spatially distributed. Here we analyse how stochastic resetting, also spatially distributed, can be used to improve the search ...

Impact of ICRF fast-ions on core turbulence and MHD activity in ASDEX upgrade
(AIP Conference Proceedings, 2023-08-18)
Experiments in various tokamaks and their analysis identify the fast ions (FI) generated by NBI and/or ICRF heating as one of the main causes of the observed improvement in core confinement: fast ions can reduce core ...

Heavy-ion induced quasi-elastic reactions in view of the NUMEN project
(Journal of Physics: Conference Series, 2023)
Double charge exchange (DCE) reactions induced by heavy ions and other direct reactions characterized by same projectile and target are crucial tools to access information relevant for neutrinoless double beta decay nuclear ...

Digital quantum simulation of an extended Agassi model: Using machine learning to disentangle its phase-diagram
(American Physical Society, 2022)
A digital quantum simulation for the extended Agassi model is proposed using a quantum platform with eight trapped ions. The extended Agassi model is an analytically solvable model including both short range pairing and ...
