Spontaneous fission of (sup 244)Cm studied by the two-velocities method at the FOBOS spectrometer

摘要

The two - velocities method was used to measure the mass - energy distribution of fission fragments (FF) originating from the spontaneous fission (sf) of (sup 244)Cm. Especially, the energy regions of cold compact (CCF) and cold deformed fission (CDF) have been investigated. The FF mass distributions of CCF- and CDF products are basically different for spontaneous and thermal neutron induced fission of Cm isotopes. Evidence for the existence of a supershort fission mode has been observed. (orig.)
