Description

Our last experiments were aimed at investigating the spontaneous fission properties of short-lived neutron-deficient isotopes synthesized in the complete fusion reaction 48Ca+ 204Pb → 252No*. Our experiment registered two short-lived activities that can be related to the spontaneous fission (SF) of ground and isomeric states of 250No. The half-life, total kinetic energies of fission fragments and neutron multiplicities were measured. The average number of neutrons per SF-activity of t1/2 = (5.1 ± 0.3) μs and t1/2 = (36 ± 3) μs were determined as ν-bar = 4.38 ± 0.13 and ν-bar = 3.90 ± 0.20, respectively.
