Recent results in nuclear astrophysics at the n_TOF facility at CERN
(Sissa Medialab, 2016)
The neutron time of flight (n_TOF) facility at CERN is a spallation source characterized by a white neutron spectrum. The innovative features of the facility, in the two experimental areas, (20 m and 185 m), allow for an ...
