Measurement of the 72Ge(n, γ) cross section over a wide neutron energy range at the CERN n_TOF facility Dietz, M. Porras Sánchez, José Ignacio Praena Rodríguez, Antonio Javier TOF Collaboration This work was supported by the Adolf Messer Foundation, the Austrian Science Fund FWF (J 3503), the Science and Technology Facilities Council UK (ST/M006085/1), the European Research Council ERC-2015-STG No. 677497, the Croatian Science Foundation under the project 8570, the MSMT of the Czech Republic, the Charles University UNCE/SCI/013 project, and by the funding agencies of the participating institutes. The 72Ge(n, γ ) cross section was measured for neutron energies up to 300 keV at the neutron time-of-flight facility n_TOF (CERN), Geneva, for the first time covering energies relevant to heavy-element synthesis in stars. The measurement was performed at the high-resolution beamline EAR-1, using an isotopically enriched 72GeO2 sample. The prompt capture γ rays were detected with four liquid scintillation detectors, optimized for low neutron sensitivity. We determined resonance capture kernels up to a neutron energy of 43 keV, and averaged cross sections from 43 to 300 keV. Maxwellian-averaged cross section values were calculated from kT = 5 to 100 keV, with uncertainties between 3.2% and 7.1%. The new results significantly reduce uncertainties of abundances produced in the slow neutron capture process in massive stars. 2021-06-01T07:20:54Z 2021-06-01T07:20:54Z 2021-04-27 info:eu-repo/semantics/article Dietz, M., Lederer-Woods, C., Tattersall, A., Battino, U., Gunsing, F., Heinitz, S., ... & n_TOF Collaboration.
