Fission studies by prompt gamma-ray spectrometry

EPJ Web of Conferences, 2015
The feasibility of retrieving accurate fission observables with a Ge-detector array around a fissile target placed in a cold neutron beam was tested. In three measurement campaigns performed at ILL with the EXILL setup, 235U and 241Pu targets were placed
