NEUTRON SPIN INTERFERENCE,PRINCIPLE OF SPINOR SUPERPOSITION AND INFLUENCE OF EARTH GRAVITY ON THE NSE

The interfererice between the spinor components of the potarized neutron beam passing through a Mezei-coil investiga-ted. The authors proposed a method to detect the phase shift of the spinor Components a to test the principle of the fermion spin superposition. The influence of the earth gravity on the spinor interference is considered. The results show that the Planck's constant h and the Newtonian gravitational constant G(or q) both are involved in the phase shift θ, which is independent of the neutron mass.
