Total Angular Momentum

"Total Angular Momentum" combines both the spin and orbital angular momentum of all particles and fields. In atomic and nuclear physics, orbital angular momentum is usually denoted by \(l\) or \(L\) instead of \(\Lambda\). The magnitude of \(J\) is quantized so that \(J^2 = \hbar^2 j(j + 1)\), where \(j\) is the total angular momentum quantum number.
