Page "Hassium" Paragraph 27

The use of a Pb-207 target was first used in 1984 at Dubna.

They were able to detect the same SF activity as observed in the Pb-208 run and once again assigned it to < sup > 260 </ sup > Sg, daughter of < sup > 264 </ sup > Hs.

The team at GSI first studied the reaction in 1986 using the method of correlation of genetic alpha decays and identified a single atom of < sup > 264 </ sup > Hs with a cross section of 3. 2 pb.

The reaction was repeated in 1994 and the team were able to measure both alpha decay and spontaneous fission for < sup > 264 </ sup > Hs.
