Absolute electron impact ionization cross sections of the M subshells of krypton have been measured. Discrepancies between the measurements and calculations by McGuire are found.doi:10.1016/0375-9601(81)90608-3Akira YagishitaElsevier B.V.Physics Letters A...
William Ramsay received the Nobel Prize for Chemistry in 1904, “in recognition of his services in the discovery of the inert gaseous elements in air, and his determination of their place in the periodic system.” He was responsible for adding an entire new group to the periodic table.Radonwa...
energy is released. This affinity is known as the first electron affinity, and these energies are negative. By convention, the negative sign shows a release of energy. However, more energy is required to add an electron to a negative ion which overwhelm...
a range of methods (X-ray photoelectron spectroscopy (XPS;Supplementary Fig. 3), XRF, high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) and thermogravimetric analysis (TGA)) confirmed the presence of successfully encapsulated lead; in particular, HAADF-STEM measurement...
Give the symbol for the element that forms a dication with the same electron configuration as the noble gas krypton.What is a Dication:Dication is a positively charged species that contains a +2 charge. Alkaline earth metals have two electrons in th...
Respective final-ion-charge spectra are found to be sensitive both to the number of initial inner-shell vacancies and to their distribution among electron subshells.doi:10.1016/S0368-2048(00)00240-1A.G. KochurElsevier B.V.Journal of Electron Spectroscopy & Related Phenomena...
The KrF+cation has been shown to behave as a Lewis acid (electron-pair acceptor) toward a number of Lewis bases that are resistant to oxidation by the strongly oxidizing KrF+cation at low temperatures. These Lewis acid-base adducts are exemplified by HCNKrF+and F3CCNKrF+, which are formed...
The ionization in the M shells was caused by electron impact. The use of a gaseous target made it possible to measure the Auger lines even at energies as low as 25 eV. The absolute energies and relative intensities of a great number of transitions were determined: 22 of the M 4, 5 ...
