The New isotope $$^{236}$$Cm and new data on $$^{233}$$Cm and $$^{237,238,240}$$Cf

Khuyagbaatar, J.*; He${ss}$berger, F. P.*; Hofmann, S.*; Ackermann, D.*; Comas, V. F.*; Heinz, S.*; Heredia, J. A.*; Kindler, B.*; Kojouharov, I.*; Lommel, B.*; Mann, R.*; Nishio, Katsuhisa   ; Yakushev, A.*

The isotope $$^{237,238,240}$$Cf were produced in irradiation of $$^{204,206,207}$$Pb targets with $$^{36}$$S ions at bombarding energies close to the Coulomb barrier. For the isotope $$^{240}$$Cf a spontaneous fission branching of 0.015 was determined. The new isotope $$^{236}$$Cm was produced by $$alpha$$ decay of $$^{240}$$Cf. It decays with 6954-keV $$alpha$$ particle emission, and half-life was determined to be 410 s. The $$alpha$$-decay of $$^{237}$$Cf was observed for the first time, and the $$alpha$$ particle energy was 8081 keV. For the isotope $$^{233}$$Cm a half-life 23 s was measured for the first time.
