We report energy distributions of electrons emitted from Al and Mg surfaces bombarded by 3-100-keV/amu hydrogen and deuterium ions. The energy spectra contain structure consistent with the decay of bulk plasmons, even below the velocity threshold expected from current theories. To explain the result...
从20世纪20年代开始,爱丁顿也研究一些与量子力学、时空有关的问题。 1936年,爱丁顿出版《质子和电子的相对论》(Relativity Theory of Protons and Electrons),论述了量子理论,研究了一些常数之间的关系。不过,他做的都是一些拼凑类型的数字游戏。例如,当物...

Angular and Energy Dependence of Cross Sections for Ejection of Electrons from Water Vapor. II. 15-150-keV Proton Impact Absolute values of cross sections for electron ejection by protons of 15-150 keV energy have been measured as a function of the angle and energy of the ele... MA Bo...
The model takes into account stripping due to collisions with ambient electrons and heavy particles (protons and He +2) which becomes increasingly important for more energetic ions, as well as radiative and dielectronic recombination due to collisions with electrons. Spatial diffusion and Coulomb ...
Mg-porphin : Analogous calculations, as for the FBP molecule, were performed also for PMg where two protons of the opposite pyrrole rings are replaced by the Mg2+ cation. This makes PMg even a more symmetric species (D4h point group of symmetry). 172 electrons create the ground state ...
What is the total charge of all the electrons in 1 g of \text{CO}_2?What is the total charge of all the electrons in 1.0 kg of H20?What is the charge of a bare Magnesium nucleus (no electrons, just the protons, and neutrons) in Coulombs?
However, the ions are not distributed evenly between the stroma and the lumen. In the dark, the concentration is higher in the latter compartment, while a redistribution occurs upon illumination. The light-driven translocation of protons into the lumen is accompanied by a release of Mg(II) ...
Origin of the forward-backward asymmetry in the decay of the giant resonance structures of 24Mg and 40Ca The decay by protons and α's of 24Mg and 40Ca excited to an energy region from about 10 to 30 MeV has been studied in an (α, α′c̅ ) experiment at E... F Zwarts,KVD...
