IEVref: 113-05-09 ID: Language: en Status: Standard Term: spin Synonym1: Synonym2: Synonym3: Symbol: Ss Definition: intrinsic angular momentum of a particleNOTE 1 The expectation value of spin in any direction is $\hslash \sqrt{s\left(s+1\right)}$ where s is spin quantum number and ħ is reduced Planck constant. NOTE 2 The spin in a given direction is quantized as multiples or half-multiples of the reduced Planck constant. In the direction of the quantization axis z, the component of the spin is quantized as Sz = msħ, ms = s, s − 1, … − s, where ms is spin magnetic quantum number and s is spin quantum number.
