Improved Mo neutron resonance parameters from neutron capture and transmission measurements at n_TOF and GELINA
R. Mucciola, S. Cristallo, S. Kopecky +140
We report high-resolution measurements of the cross section in the neutron energy range from a few eV up to about 250 keV, performe…
First Nb() Measurement: Constraining the Nucleosynthetic Origin of Mo in Presolar Grains
J. Balibrea-Correa, J. Lerendegui-Marco, C. Domingo-Pardo +136
Isotopic measurements of presolar silicon carbide grains from dying stars have revealed a puzzling overabundance of Mo that stellar nucleosynthesis models have failed to rep…
Constraining r-process nucleosynthesis via enhanced accuracy neutron-capture experiments
C. Domingo-Pardo, C. Lederer-Woods, A. Mengoni
The isotopic abundances of r-process elements in the solar system are traditionally derived as residuals from the subtraction of s-process contributions from total solar abundances…
Slow White Dwarf Mergers as a New Galactic Source of Trans-Iron Elements
Umberto Battino, Claudia Lederer-Woods, Claudia Travaglio +2
The astrophysical origins of the heaviest stable elements that we observe today in the Solar System are still not fully understood. Recent studies have demonstrated that H-accretin…
Impact of newly measured 26Al(n, p)26Mg and 26Al(n, α)23Na reaction rates on the nucleosynthesis of 26Al in stars
Umberto Battino, Claudia Lederer-Woods, Marco Pignatari +6
The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites…
Radiative neutron capture cross section of Pu measured at n_TOF-EAR1 in the unresolved resonance region up to 600 keV
J. Lerendegui-Marco, C. Guerrero, E. Mendoza +133
Accurate neutron capture cross sections are essential for the design and operation of fast reactors using MOX fuels. For Pu, the Nuclear Energy Agency (NEA) recommends 8--1…
