FLEROV LABORATORY of NUCLEAR REACTIONS

Joint FLNR Seminar

On Wednesday, 5 October 2016, at 3.30 pm in the Conference hall of the Flerov Laboratory of Nuclear Reactions a seminar “Half a century gas phase chemistry in transactinide research” will be held.

Speaker: H.W. Gaeggeler (Paul Scherrer Institut and Bern University, Switzerland)

Abstract:

1966 I. Zvara et al. published a manuscript that described a gas chemical study of Rf, the first transactinide element. Since then gas chemical techniques have been widely used to investigate chemical properties of heaviest elements. Two versions of this technique were applied: isothermal gas chromatography and thermochromatography. On the basis on less than 10 atoms first ever chemical investigations of Rf, Db, Sg, Bh, Hs, Cn, Nh, and Fl were conducted at FLNR in Dubna, GSI Darmstadt, and PSI Villigen. The talk summerizes the history of these experiments and at the end gives an outlook to a possible first ever gas chemical study of the heaviest element known today, Oganesson (Z=118).
