Abstract

The problem of studying the spontaneous fission of nuclei from the exotic region of short�lived neutron�deficient isotopes with Z ≥ 100 is considered. A combined detecting system is created in the focal plane of the VASSILISSA separator. The main part of this system is a neutron detector that allows us to mea�sure the yields of spontaneous fission neutrons from nuclei produced in a total fusion reaction with heavy ion beams in the on�line mode. This procedure is used for the first time to acquire data on the emission of spon�taneous fission neutrons from short�lived 244,246Fm isotopes. Data gathered earlier for 252No isotopes are refined in the scope of this work.
