Simultaneous measurement of neutron-induced capture and fission reactions at CERN

The measurement of the capture cross-section of fissile elements, of utmost importance for the design of innovative nuclear reactors and the management of nuclear waste, faces particular difficulties related to the -ray background generated in the competing fission reactions. At the CERN neutron tim...
