Abstract：
The interference between the spinor components of the polarized neutron beam passed through a Mezei-coil, i.e. spin interference, is investigated. The influence coming from the earth gravitation on the Neutron Spin Echo(NSE) is calculated. We point out that this quantum interference effect due to gravitation will not violate the weak principle of equivalence, so it has a significant diffrence to the COW experiment.
