Answer to Question #156503 in Quantum Mechanics for Satyam

Question

Spin of paticles explain.

Answer 1

Answer

The spin is the total angular momentum, or intrinsic angular momentum of any system or body. .according to Physics concept The spins of elementary particles are accounted to the spins of macroscopic bodies.

Now the total angular momentum, which is the sum of spin angular S momentum and orbital angular momentum l , and also in the isolated systems the total angular momentum is conserved. ... When they annihilate their spins cancel. So spin is conserved like charge is conserved. This all about spins.
