A nomograph for electron number transmission and an expression for the differential energy spectra of the penetrating electrons are developed from Monte Carlo calculations of normal incident electrons on slabs of beryllium, aluminum, iron, silver, and lead with energies in the range of 0.4 to 10 Me...

For the quadrupole moment they are known as Sternheimer corrections. ...
Various systems have been developed in order to stop corrosion processes on metallic substrates. The corrosion process itself occurs in the presence of an electrochemical couple, i.e., in the presence of metals that have a high tendency for the exchange of electrons. This setup is equivalent to...
The newly formed electron then collides with another argon atom such that a chain reaction or ionization reaction is started. When the electrons bombard the wafer surface, the surface may be charged to a negative voltage higher than 30 volts. [0006] One of the more important components in a...
Electron creep occurs when individual electrons migrate across a surface in between the positive and negative poles, said electrons being effectively extracted from the negative pole. This effect becomes more notable as the electric potential increases to higher values or when the metal parts are very...
Electrons in an atom can be found in several orbits. The first orbit can contain two electrons in total. Additional orbits contain various numbers of electrons, with the outermost orbit known as the valence orbit. The electron shielding effect mainly applies to the valence electrons. Electrons fou...

Ions are produced in Hall thrusters when electrons from an electric current collide with the propellant atoms to form a plasma in the discharge chamber. Thrust is then generated by the interaction of this current with an applied magnetic field that creates a strong electric field. The magnetic fi...
