Derivation of quantized angular momentum
WebDec 8, 2024 · 7: Orbital Angular Momentum and Spin. 7.2: Spin. Pieter Kok. University of Sheffield. From classical physics we know that the orbital angular momentum of a particle is given by the cross product of its position and momentum. L = r × p or Li = ϵijkrjpk, where we used Einstein’s summation convention for the indices. http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/qangm.html

WebDec 24, 2024 · Spin is quantized in the same manner as orbital angular momentum. It has been found that the magnitude of the intrinsic spin angular momentum \(S\) of an electron is given by \[S = \sqrt{s(s + 1)}\hbar, \nonumber \] where \(s\) is defined to be the spin quantum number. This is similar to the quantization of \(L\), except that the only value ... WebIn physics, angular momentum (sometimes called moment of momentum or rotational momentum) is the rotational analog of linear momentum. It is an important physical …
WebFeb 1, 2024 · I understand that Bohr postulated that electrons can only occupy orbits at certain radii, and that in order to move from one orbit (or stationary state) to another, it would have to absorb or emit a quantum of energy from a photon. WebSep 20, 2024 · The Bohr's postulate of quantisation of angular momentum can be written in a formula as m v r = n h / ( 2 π) where m is mass of electron. v is its velocity. r is the radius of that shell. h is Plank's constant. So, I was wondering that if, I want to find where approximately the thing with n = 2 exists, or in other words, what is the velocity ...
WebSep 12, 2024 · Figure 8.2.1: A representation of the Bohr model of the hydrogen atom. With the assumption of a fixed proton, we focus on the motion of the electron. In the electric field of the proton, the potential energy of the electron is. U(r) = − ke2 r, where k = 1 / 4πϵ0 and r is the distance between the electron and the proton. WebJul 27, 1999 · The results of classical angular momentum provide a clear physical model for representation of orbital and spin angular momentum in terms of the vector model. Let us now consider the new features that are introduced by the laws of quantum mechanics which spin angular momentum (both electronic and nuclear) must obey.
