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 ...

Destruction of the cosmic γ-ray emitter 26 Al in massive stars: Study of the key 26 Al ( n , p ) reaction
(American Physical Society, 2021)
The 26 Al (n ,p) 26 Mg reaction is the key reaction impacting on the abundances of the cosmic y-ray emitter 26 Al produced in massive stars and impacts on the potential pollution of the early solar system with 26 Al by ...

First results of the140ce(N,ү)141ce cross-section measurement at n_tof
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
An accurate measurement of the140Ce(n,ү) energy-dependent cross-section was performed at the n_TOF facility at CERN. This cross-section is of great importance because it represents a bottleneck for the s-process nucleosynthesis ...

A compact fission detector for fission-tagging neutron capture experiments with radioactive fissile isotopes
(Elsevier, 2020)
In the measurement of neutron capture cross-sections of fissile isotopes, the fission channel is a source of background which can be removed efficiently using the so-called fission-tagging or fission-veto technique. For ...

Dispersive optical model description of nucleon scattering on Pb and Bi isotopes
(American Physical Society, 2020)
A recently derived dispersive optical model potential (DOMP) for 208Pb is extended to consider the nonlocality in the real potential and the shell gap in the definition of the nuclear imaginary potentials near the Fermi ...
