Recently a new specific interest for fission yields of "minor" actinides arose, due to the development of new reactor technologies and transmutation project of actinides and nuclear wastes. The SPIN program (for SeParation-INcineration) has been launched at the CEA (Commisariat a I'energie atomique, France) to search for solutions allowing to partition and transmute long-Iived radiowaste in order to reduce their volume and toxicity and to investigate new fuel cycles.

From the standpoint of the inventory of transuranium elements in Pressurised Water Reactor (PWR) and of their radiotoxicity. Curium and in particular Curium 245 is the third most important nuclide after Plutonium and Americium. Within these aspects we investigated the reaction (245) Cm(n(th),f) at the mass spectrometer Lohengrin. A new technique using an ionisation chamber and an absorber has allowed to measure the isotopic yields from Z=34 (Se) up to Z=47 (Ag.) Moreover, mass and kinetic energy distributions up to mass A=167 have been investigated. We present the measurement techniques and preliminary results. .
