free electron - electron that is not attached to an atom or ion or molecule but is free to move under the influence of an electric field lepton - an elementary particle that participates in weak interactions; has a baryon number of 0 photoelectron - an electron that is emitted from an atom...
The effective-mass formalism is shown capable to describe the fully relativistic motion of an electron in a strong, locally plane, electromagnetic wave, determining the drift caused by the wave inhomogeneity and by additional weaker fields. The limits of this approach are discussed, in connection ...
Electron Mass In subject area: Earth and Planetary Sciences Electron mass refers to the mass of an electron, which is approximately 1/1836 times the mass of a proton. It is a fundamental property used in determining the mass density of matter systems. AI generated definition based on: Encyclop...

What is electron, it is the lightest stable subatomic particle. It has a negative charge that is the basic unit of the electric charge. The mass of an electron at rest is 9.10938356 x 10-31 kg that is only 1/1,836 the mass of a single proton.
英语翻译Calculate the energy of an electron with mass 9.109 × 10–31 kg confined in a 2-dimensional box with sides of length 1.50 nm given quantum numbers nx=4 and ny=3. 答案 翻译:请计算一个质量为9.109 × 10–31 kg,被束缚在边长为1.50 nm的2维盒子里面的电子的能量.规定量子数nx=4,ny...
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 design requirements to detect the small signature of a neutrino mass in the last few electron-volts of theβ-decay spectrum are a high tritium activity (1 × 1011 Bq), a low background rate (≲0.1 counts per second (cps)), an electron-volts-scale energy resolution and ...
C.R. Pidgeon, in Encyclopedia of Modern Optics, 2005 Effective Mass Consider what happens to an electron when an external electric field F is applied. Suppose the electron is initially in a state k. When the field has acted on the electron for a small time dt, it has gained an energy:...
If the Doppler shifts of spectral lines as a function of time can be measured for both components, then the period can be determined as well as the mass ratio and minimum masses of the components. If in addition the system shows an eclipse, then the individual masses can be determined. ...
