Physically, we know that there are spin 1/2 particles. A spin 1/2 field cannot be described by anything built from 4-vector fields. You can realize this for example by that 4-vector fields (and so anything built from them) returns to their original value after a $2\pi$ rotation whereas a spin 1/2 .   In general, bound states of identical neutrons are possible. They're called "neutron stars", and it is the force of gravity that holds them together. I guess two neutrons could be bound by a gravitational interaction, but gravity is so weak that it would be a huge state. And of course neutrons decay in only 20 minutes. using a suitable Hamiltonian operator Ĥ corresponding to the system. The solution is a complex-valued wavefunction ψ(r, t), a function of the 3D position vector r of the particle at time t, describing the behavior of the system.. Every particle has a non-negative spin quantum number number 2s is an integer, odd for fermions and even for s has 2s + 1 z-projection quantum. Facts and mysteries in elementary particle physics.
