The kinetic energy of electrons and the potential energy of a nitrogen atom with open electron shell are calculated in this work in the basis of the Slater functions using the Hartree–Fock–Roothaan (HFR) method. Analytical expressions are derived for the kinetic and potential energies of the ...
This energy is close to the maximum capture cross-section of most common MALDI matrices, leading to the efficient formation of negative matrix ions. This results in the reduction of the positive analyte ion yield. The effect can be minimized by shifting the kinetic energy of the electrons away...
Using a modified MKh1320 mass spectrometer as described, the authors measured positive and negative ions and electrons produced by ionization of gases at a pressure up to 10{sup 2} Pa. Initial kinetic energies of charged species exiting the ion source of the mass spectrometer were determined by...
Tags Electron Energy Kinetic Kinetic energy In summary, when ultraviolet light with a wavelength of 60.0 nm shines on a gas of hydrogen atoms in their ground states, some of the atoms are ionized, freeing electrons. To determine the kinetic energy of these electrons, the equation En = n2h2...
