Electrons behave both as particles and as waves, and their motion generates electric and magnetic fields. Though the electron is the lightest subatomic particle, its charge is as great as that of a proton. See more at atom. The American Heritage® Student Science Dictionary, Second Edition. ...
A. S. Eddington reached the conclusion that the value of the physical constant ch/2蟺eis given by the integer 136. His theory reduces the evaluation of this constant essentially to the counting up of symmetrical elements in a square array. The numbers of such elements in arrays arising in ...
The rest mass of an electron is the mass of a stationary electron, also known as the electron invariant mass. The charge to mass ratio of electron is e/m is the ratio between the charge of the electron by the mass of the electron which is 1.758820 - 10^1
The UW Penning trap mass spectrometer has been used to improve the values for the electron's atomic mass and the proton-electron mass ratio. The cyclotron frequency of small clouds of /spl les/15 electrons is compared with the cyclotron frequency of a single trapped carbon ion (C/sup 6+/...

4) electron mass 电子质量 1. The electron mass is measured, and the linewidth of the coherent scattering is analyzed. 测量了电子质量,分析了相干散射线宽,测量了非相干散射光子的能量,算出了非相干散射微分截面,给出了Θ~Θ+dΘ内散射光子微分截面与散射角关系。5) hydrogen to proton mass ratio ...
We use a rovibrationally pure sample of ultracold KRb molecules to improve the measurement on the stability of electron-to-proton mass ratio ($\\\mu = \\\frac{m_{m e}}{M_{m p}}$). The measurement is based upon a large sensitivity coefficient of the molecular spectroscopy, which...
Electron, lightest stable subatomic particle known. It carries a negative charge of 1.6 x 10^-19 coulomb, which is considered the basic unit of electric charge. The electron was discovered in 1897 by the English physicist J.J. Thomson during investigatio
Proton and Electron Mass-Energy Equivalence to Displaced Vacuum Energy By: Ray Fleming Abstract Two of the great mysteries of physics are the origin of mass, and the mysterious mass ratio between the proton and electron of ~1836. In this paper it is shown that the mass-energy of the proton...
