The atomic structure of californium is probed by two-step resonance ionization spectroscopy. Using samples with a total amount about 2×1010 Cf atoms (ca. 8.3 pg), ground-state transitions as well to high-lying Rydberg states and auto-ionizing above the potential are investigated lifetimes various levels measured. These investigations lead identification efficient schemes, important for trace an...

The total kinetic energy (TKE) of fission fragments for some heavy actinides is investigated and calculated using the scission point model. First, deformation parameters are obtained by fitting results to available experimental data. Then, behavior TKE distribution fission. This indicates that Usang model can better explaine heavier than californium Unik Also, value be approximated sum Coulomb ...
