The absolute cross section for the double ionization of 0953-4075/31/3/004/img2 from threshold to 500 eV has been measured for the first time. A combination of electron beam modulation and fast energy-scanning techniques was used. At energies around 340 eV the cross section displays several ...
The internal ionization accompanying the first-forbidden unique electron-capture decay of 41Ca was investigated. The integrated probability of electron ejection with energy greater than 38keV was found to be (0.17 卤 0.02) 脳 10 5 per K-capture. In this energy range, the measured spectrum of ...

The energy resolution is approximately 0.15 eV by measuring the FWHM of the ZLP. The exposure time for each probe position is 4 s. The in-situ heating experiment was performed inside the Thermo Scientific Talos F200X TEM. The Protochips heating E-chip was first mounted onto the Proto...
vertical ionization potential,and vertical electron afnity.The results show that the charges in corresponding Ca2Sin clusters transfer from the Ca atoms to the Sin host.Based on the obtained lowest-energy geometries,the size dependence of cluster properties,such as averaged binding energies,...
First, both secondary amines were reacted in the presence of commercial 4-fluorobenzenesulfonamide (16) and 3,4-difluorobenzenesulfonamide (17) via a green chemical reaction named aromatic nucleophilic substitution. The latter was performed in H2O at reflux to produce pure intermediates 18–21. ...
