Fairly often, the "spin quantum range" is simply known as "spin". The fact that It's a quantum quantity is implicit. So when physicists evaluate the spin of the particle together the x-axis as, for example, ħ/2, the particle's spin state collapses in to the eigenstate ∣ ψ x + ⟩ https://archkala.ir/%d9%84%db%8c%d9%84%db%8c-%d8%b1%db%8c-%d8%a7%d8%b2-path-interactive-%d8%b1%d9%be%d9%88%d8%b1%d8%aa%d8%a7%da%98-%d8%a2%da%af%d9%87%db%8c/
