Description

A new nuclide 263Ha was produced in the bombardment of a 249Bk target with 93-MeV 18O ions. It was detected via spontaneous fission counting and was shown to have a half-life of about 0.5 min. This activity was also separated from the reaction products by automated rapid chemical separations using cation-exchange chromatography in 0.05M α-hydroxyisobutyric acid. After chemical separation, 263Ha was found to decay by spontaneous fission (57-15+13%) and by α emission (Eα=8.35 MeV, 43%) with a half-life of 27-7+10 s. The spontaneous fission fragment energy spectrum is compatible with an average total kinetic energy of about 200 MeV
