Measurement and resonance analysis of the 33S(n,α) 30Si cross section at the CERN n_TOF facility in the energy region from 10 to 300 keV
(American Physical Society, 2018-06-04)
The 33S(n,α) 30Si cross section has been measured at the neutron time-of-flight (n_TOF) facility at CERN in the neutron energy range from 10 to 300 keV relative to the 10B(n,α) 7 Li cross-section standard. Both reactions ...

Measurement and analysis of 155,157Gd(n,γ) from thermal energy to 1 keV
(EDP Sciences, 2020)
We have measured the capture cross section of the 155Gd and 157Gd isotopes between 0.025 eV and 1 keV. The capture events were recorded by an array of 4 C6D6 detectors, and the capture yield was deduced exploiting the total ...

Study of photon strength functions of 241Pu and 245Cm from neutron capture measurements
(EDP Sciences, 2020)
We have measured the γ-rays following neutron capture on 240Pu and 244 Cm at the n_TOF facility at CERN with the Total Absorption Calorimeter (TAC) and with C6D6 organic scintillators. The TAC is made of 40 BaF2 crystals ...

Neutron Capture on the s-Process Branching Point Tm 171 via Time-of-Flight and Activation
(American Physical Society, 2020)
The neutron capture cross sections of several unstable nuclides acting as branching points in the s process are crucial for stellar nucleosynthesis studies. The unstable Tm171 (t1/2=1.92 yr) is part of the branching around ...
