Populating α-unbound states in 16O via 19F (p, αy)16O reaction [PDF]

open access: yesEPJ Web of Conferences, 2023
The 12C(α, y)16O reaction is important in the production of universal 16O, but its cross-section at the relevant energies of static helium burning is complex and uncertain.

Evaluation of water equivalent thicknesses using the IEM-CSIC scanner prototype [PDF]

open access: yesEPJ Web of Conferences, 2023
Proton imaging has been proposed as an alternative low-dose imaging technique for acquiring relative stopping power (RSP) maps and for patient positioning. In proton therapy and hadrontherapy, the water equivalent thickness (WET) of a material represents

Reaction studies with neutron-rich light nuclei at the upgraded SEC Device: Exploring the excited structure of 11Li [PDF]

open access: yesEPJ Web of Conferences, 2023
The 11Li nucleus is considered the best example of a two-neutron halo nucleus. While the structure of the ground state is well established there is still a significant debate regarding its excited states despite of the multiple experiments realised ...

Scattering of 15C on 208Pb at energies near the Coulomb barrier: Study of the experimental device response via the 12C+208Pb scattering [PDF]

open access: yesEPJ Web of Conferences, 2023
There are evidences that the 15C nucleus has an extended neutron distribution or a "neutron halo", but this situation is far from clear. If 15C has 1n-halo, the scattering dynamics should be affected and the angular distribution of the elastic channels ...

Illicit financial flows and the provision of child and maternal health services in low- and middle-income countries

open access: yesBMC International Health and Human Rights, 2020
Background Illicit financial flows (IFFs) drain domestic resources with harmful social effects, especially in countries which are too poor to mobilise the revenues required to finance the provision of essential public goods and services. In this context,
