74 Ge(n, γ) cross section below 70 keV measured at n_TOF CERN
(Springer Nature, 2022)
Neutron capture reaction cross sections on 74Ge are of importance to determine 74Ge production during the astrophysical slow neutron capture process. We present new resonance data on 74Ge(n, γ) reactions below 70 keV neutron ...

High accuracy, high resolution 235U(n,f) cross section from n_TOF (CERN) from 18 meV to 10 keV
(Springer Nature, 2022)
The 235U(n,f) cross section was measured in a wide energy range (18 meV–170 keV) at the n_TOF facility at CERN, relative to 6Li(n,t) and 10B(n,α) standard reactions, with high resolution and accuracy, with a setup based ...

Self-diffusion in a quasi-two-dimensional gas of hard spheres
(American Physical Society, 2020)
A quasi-two-dimensional system of hard spheres strongly confined between two parallel plates is considered. The attention is focused on the macroscopic self-diffusion process observed when the system is seen from above or ...

Connecting the global H-mode power threshold to the local radial electric field at ASDEX Upgrade
(IOP Publishing, 2020)
The relation between the macroscopic input power required at ASDEX Upgrade to access the H-mode Pthr and the microscopic E x B shear has been investigated via fast charge-exchange recombination spectroscopy (CXRS) measurements ...

Reaction Theory and Advanced CDCC
(Institute of Physics Publishing, 2020)
The Continuum-Discretized Coupled-Channels (CDCC) has been successfully employed to describe elastic and breakup of nuclear reactions induced by weakly bound projectiles. In this contribution, we review some other, less ...

Derivation of the Casimir contribution to the binding potential for 3D wetting
(Taylor & Francis, 2023)
The renormalisation group theory of critical and tri-critical wetting transitions in three-dimensional systems with short-ranged forces, based on analysis of an effective Hamiltonian with an interfacial binding potential ...

An Approach to Interfacing the Brain with Quantum Computers: Practical Steps and Caveats
(Old City Publishing, 2022)
We report on the first proof-of-concept system demonstrating how one can control a qubit with mental activity. We developed a method to encode neural correlates of mental activity as instructions for a quantum computer. ...

I-mode pedestal relaxation events at ASDEX Upgrade
(IOP Publishing, 2020)
The I-mode confinement regime can feature small edge temperature drops that can lead to an increase in the energy deposited onto the divertor targets. In this work, we show that these events are associated with a relaxation ...

A Segmented Total Energy Detector (sTED) optimized for (n, ) cross-section measurements at n_TOF EAR2
(Elsevier, 2024-04)
The neutron time-of-flight facility n_TOF at CERN is a spallation source dedicated to measurements of neutron-induced reaction cross-sections of interest in nuclear technologies, astrophysics, and other applications. Since ...

Study of the neutron-induced fission cross section of 237Np at CERN's n_TOF facility over a wide energy range
(EDP Sciences, 2020)
Neutron-induced fission cross sections of isotopes involved in the nuclear fuel cycle are vital for the design and safe operation of advanced nuclear systems. Such experimental data can also provide additional constraints ...
