Abstract
Neutron induced fission cross sections of several isotopes have been measured at the CERN n-TOF spallation neutron facility. Between them some measurements involve isotopes (233U, 241Am, 243Am, 245Cm) relevant for applications to nuclear technologies.
The n-TOF facility delivers neutrons with high instantaneous flux and in a wide energy range, from thermal up to 250 MeV. The experimental apparatus consists of an ionization chamber that discriminates fission fragments and α particles coming from natural radioactivity of the samples.
All the measurements were performed referring to the standard cross section of 235U.
