Times Cited Count：103 Percentile：98.86(Chemistry, Inorganic & Nuclear)We report on a gas-solid chromatography study of the adsorption of element 114 (flerovium, Fl) on a Au surface. Fl was produced in the nuclear fusion reaction 
Pu(

Fl and was isolated in-flight from the primary beam in a physical recoil separator. The adsorption behavior of Fl, its nuclear 
-decay product Cn, their lighter homologues in groups 14 and 12, i.e., Pb and Hg, and the noble gas Rn were studied simultaneously by isothermal gas chromatography and thermochromatography. Two Fl atoms were detected. They adsorbed on a Au surface at room temperature, but not as readily as Pb and Hg. The observed adsorption behavior of Fl points to a higher inertness compared to its nearest homologue in the group, Pb. However, the measured lower limit for the adsorption enthalpy of Fl on a Au surface points to the formation of a metal-metal bond of Fl with Au. Fl is the least reactive element in the group, but still a metal.

The analysis of a large body of heavy ion fusion reaction data with medium-heavy projectiles (6
Z18) and actinide targets suggests a disappearance of the 3 exit channel with increasing atomic number of the projectile. Here, we report a measurement of the excitation function of the reaction Cm(Mg,
)
Hs and the observation of the new nuclide Hs produced in the 3 evaporation channel at a beam energy well below the Bass fusion barrier with a cross section comparable to the maxima of the 4 and 5 channels. This indicates the possible discovery of new neutron-rich transactinide nuclei using relatively light heavy ion beams of the most neutron-rich stable isotopes and actinide targets.
