Abstract IT has recently been suggested by Bondi and Ly ttleton1,2that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In fact, Piccard and Kessler3...

Charge asymmetry in electron (positron) scattering arises from the interference of the Born amplitude and the box-type amplitude corresponding to two virtual photons exchange. It can be extracted from electron-proton and positron-proton scattering experiments, in the same kinematical conditions. Consideri...
The observed fractional charge in the absence of frontier band misalignment arises from a significant overlap between the proton and the electron density from the metal surface, and results in an energetic difference between protons in bulk solution and those in the outer Helmholtz plane....

The electron affinities are energetically destabilized while energetic stabilization of the radical-cation increases by decreasing the thiophene rings from four to one. The perfluoroarene rings leads to enhance the electron injection. 展开 关键词: Optical materials HOMO LUMO Optical properties ...
An electron is a subatomic particle commonly represented as e- or e. It posses negative polarity. Know the value of Electron like its mass, charge and spin and units.
