A second-order differential equation is derived for the electric potential of an electron system with slowly varying density. It includes consistently the first-gradient corrections to both the kinetic energy and the exchange energy. In the regime of high density, the equation reduces to the one ...
A quantum-mechanical investigation has been carried out to determine the energy eigenvalues of an electron moving in the field of a finite electric quadrupole, having point charges -q,+2q, and -q arranged collinearly with each negative charge a distance scra from the positive charge. When the...
The electron-energy equation for an atomic radiating plasma is considered in this work. Using the atomic model of Bates, Kingston and McWhirter, the radiation loss-term valid for all optical thicknesses is obtained. A study of the energy gained by electrons in inelastic collisions shows that ...
Step by step video & image solution for Energy of an electron is given by E = - 2.178 xx 10^-18 J ((Z^2)/(n^2)). Wavelength of light required to excite an electron in an hydrogen atom from level n = 1 to n = 2 will be (h = 6.62 xx 10^-34 Js and c = 3.0 xx 10^...
The core-electron binding energies (CEBEs) of dioxolane37and five other C3H6O2structural isomers were computed at the DFT level and were compared with X-ray photoelectron spectra (Scheme 26) [00IJQ44a]. The results are in a good agreement with an average deviation of 0.15eV. MP2/6-311G(...
An electron-positron equation of state based on table interpolation of the Helmholtz free energy is developed and analyzed. The interpolation scheme guarantees perfect thermodynamic consistency, independent of the interpolating function. The choice of a biquintic Hermite polynomial as the interpolating funct...
band energy in the tight bonding model, 𝑒e is the unit electron charge, and 𝐷𝐶𝑁𝑇DCNT is the diameter of CNTs, as calculated in Equation (3). By considering (1) through (4), we can conclude that the threshold voltage of CNFETs depends on the diameter of the under-gate ...
These systems capture the kinetic energy of the wind through the aerodynamic blades of the wind turbine and use it to rotate the generator (PMSG), which in turn generates electrical power. The fundamental equation describing the mechanical power of the wind turbine is given by: 𝑃𝑎𝑒𝑟...

Here we present a method based on the energy-participation ratio (EPR) of a dissipative or nonlinear element in an electromagnetic mode. The EPR, a number between zero and one, quantifies how much of the mode energy is stored in each element. The EPRs obey universal constraints and are ...
