Summary: | The surrogate reaction method is a powerful tool to infer neutron-induced data of short-lived nuclei. After a short overview of the experimental techniques employed in the present surrogate experiments, we will concentrate on a recent measurement to determine neutron-induced fission cross sections for the actinides 242,243Cm and 241Am. The latest direct neutron-induced measurement for the 243Cm fission cross section is questioned by our results, since there are differences of more than 60% in the 0.7 to 7 MeV neutron energy range. Our experimental set-up has also enabled us to measure for the first time the fission fragment 'pseudo-mass' distributions of 243,244,245Cm and 242Am compound nuclei in the excitation energy range from a few MeV to about 25 MeV. |
