The Inorganic Radiochemistry of Heavy Elements

Gas chemical properties of heaviest elements

“…PFA capillary (8) connecting oven (7) with a getter oven (9) filled with heated Ta and Ti foils (10). Detector array with H 2 O cooling on the entrance side (11) and liquid nitrogen cooling on the other (14). Au covered metal plates (12) and 32 1 × 1 cm 2 size PIN detectors (13).…”

“…The solid lines depict results of a Monte Carlo model prediction (left axis in rel. yield) including the given experimental parameters and assuming the deposited atoms to have always an adsorption enthalpy with the Au surface of −52 kJ/mole [14]. The vertical dashed lines at detectors 17, 19, and 21, respectively, indicates the start of ice layer formation towards lower temperatures as clearly seen in reduced resolutions in the α-spectra (from [35]).…”

“…• C is from a decay during the transport [14,47]. This yields an adsorption enthalpy for element 114 on Au of 34 +20 −3 kJ/mole [45].…”

“…τ 0 is a constant. In real experiments single atoms are subjected to up to 10 5 interactions [14]. In single atom chemistry reaction rates have to be quantified on the basis of statistical probabilities, derived from the chemical equations, but coupled to Monte Carlo models in order to predict trajectories of individual species in a given system (see e.g.…”

“…In single atom chemistry reaction rates have to be quantified on the basis of statistical probabilities, derived from the chemical equations, but coupled to Monte Carlo models in order to predict trajectories of individual species in a given system (see e.g. [14] [15]). This manuscript concentrates on the recent gas chemical experiments with Cn, element 113 and 114.…”
