Do Bosons Have Spin?

Bosons are those particles which have an integer spin (0, 1, 2...). All the force carrier particles are bosons, as are those composite particles with an even number of fermion particles (like mesons).

Why do bosons have integer spin?

Why do bosons have "integer" spins? A: It's a matter of definition. It is determined by experiment that a certain class of fundamental particles like electrons, protons, etc, all have half integer spin values in terms of the fundamental unit of angular momentum h/2pi where h is Plank's constant.

How many spins do bosons have?

Bosons and fermions act like two different kinds of spinning tops. Even when a boson or fermion is by itself, it always has an intrinsic angular momentum, which scientists call spin. Bosons always have an integer amount of spin (0, 1, 2...), while fermions have half-integer spin (1/2, 3/2, 5/2...).
