If the kinetic energy of an electron is 270 eV, calculate its De Broglie wavelength. (Note: For this non-relativistic electron, first calculate its velocity from the general kinetic energy equation. T What is the kinetic ener...
What is the kinetic energy in eV of an electron whose de Broglie wavelength is 19% of the wavelength of a photon having the energy equal to electrons kinetic energy? How fast must an electron move to have a kinetic ene...
To solve the problem step by step, we will calculate the velocity, momentum, and wavelength of the electron using the given kinetic energy and mass.Step 1: Calculate the Velocity of the Electron The kinetic energy (KE) of an el
Electron-impact ionization cross-sections of alkali-metal atoms and noble-gas atoms have been calculated using Gryzinski's, Vriens' and Burgess' formulae. The kinetic energy of the bound electron has been estimated by using Slater's rule. Comparisons have been made with experimental results....

A kinetic-energy functional of the electronic density is presented. This functional is based on an integral form and is correct through second order in the response. The formulas are compared numerically with the Thomas–Fermi–von Weizsäcker–like formulas and favorable results are found. These...
