Scattering of the halo nucleus 11Be from a lead target at 3.5 times the Coulomb barrier energy
(Elsevier, 2020)
Angular distributions of quasielastic scattering and breakup of the neutron-rich halo nucleus 11Be on a 208Pb target at an incident energy of 140 MeV (about 3.5 times the Coulomb barrier) were measured at HIRFL-RIBLL. A ...

Beam-Ion Acceleration during Edge Localized Modes in the ASDEX Upgrade Tokamak
(American Physical Society, 2018-07)
The acceleration of beam ions during edge localized modes (ELMs) in a tokamak is observed for the first time through direct measurements of fast-ion losses in low collisionality plasmas. The accelerated beamion population ...

Searching for universality of dineutron correlation at the surface of Borromean nuclei
(Elsevier, 2023-05-10)
The dineutron correlation is systematically studied in three different Borromean nuclei near the neutron dripline, 11Li, 14Be and 17B, via the knockout reaction measured at the RIBF facility in RIKEN. For the three ...

New evaluation of the axial nucleon form factor from electron- and neutrino-scattering data and impact on neutrino-nucleus cross sections
(American Physical Society, 2020)
A joint fit to neutrino-nucleon scattering and pion electroproduction data is performed to evaluate the nucleon axial form factor in the two-component model consisting of a three-quark intrinsic structure surrounded by a ...

Feasibility study for an edge main ion charge exchange recombination spectroscopy system at ASDEX Upgrade
(IOP Publishing, 2019)
A feasibility study for a new edge main ion charge exchange recombination spectroscopy (CXRS) system at the ASDEX Upgrade tokamak has been carried out. This diagnostic uses the new edge fast-ion Dα (FIDA) spectrometers and ...

Oxygen-15+ resonant elastic scattering to study cluster states in 19Ne
(Institute of Physics Publishing, 2017)
The elastic scattering excitation function for 15O on 4He was measured - for the first time - by using the Inverse Kinematic Thick Target scattering method. The obtained spectrum was analysed in an R-matrix framework ...

MHD Simulations of Formation, Sustainment and Loss of Quiescent H-mode in the All-tungsten ASDEX Upgrade
(Institute of Physics Publishing, 2023)
Periodic edge localized modes (ELMs) are the non-linear consequences of pressure-gradient-driven ballooning modes and current-driven peeling modes becoming unstable in the pedestal region of high confinement fusion plasmas. ...

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 ...

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 ...
