Status and outlook of the neutron time-of-flight facility n_TOF at CERN
Gunsing, F.; Abbondanno, U.; Aerts, G.; Alvarez, H.; Álvarez-Velarde, F.; Andriamonje, S.; Andrzejewski, J.; Assimakopoulos, P.; Audouin, L.The neutron time-of-flight facility n_TOF at CERN, fully operational since 2002, combines a high instantaneous neutron flux with high energy resolution. The wide energy range and the high neutron flux per time-of-flight burst result in a much enhanced signal to background ratio for neutron capture of radioactive isotopes and makes this facility well suited for the measurement of high quality neutron-induced rea...
Neutron reactions and nuclear cosmo-chronology
Mosconi, M.; Heil, M.; Käppeler, F.; Mengoni, A.; Plag, R.; Fujii, K.; Gallino, R.; Aerts, G.; Terlizzi, R.; Abbondanno, U.; Álvarez-Pol, H.The [beta]-decay of 187Re represents a suited cosmo-chronometer for the age of the r-process abundances, since the radiogenic part of the daughter isotope 187Os is defined by the difference between the solar 187Os abundance and s-process contribution to 187Os. The latter component can be determined via the s-process systematics based on the stellar neutron capture cross sections of 186Os and 187Os. The laborato...
