spin science definition
- The intrinsic angular momentum of a rigid body or particle, especially a subatomic particle. Also called spin angular momentum.
- The total angular momentum of a physical system, such as an electron orbital or an atomic nucleus.
- A quantum number expressing spin angular momentum; the actual angular momentum is a quantum number multiplied by Dirac's constant. Fermions have spin values that are integer multiples of 1/2 , while bosons have spin values that are integer multiples of 1.
