摘要： Along the geodesic we calculate the interference phase of the mass neutrinos propagating in the radial direction in Robertson--Walker space--time. Since our universe is expanding, the phase factor Ph is increasing under the condition of the same proper physical distance l. Different values of curvature parameter k in Robertson--Walker metric represent different cosmological models, correspondingly, we obtain the different interference phases.

Abstract: Along the geodesic we calculate the interference phase of the mass neutrinos propagating in the radial direction in Robertson--Walker space--time. Since our universe is expanding, the phase factor $\varPhi$ is increasing under the condition of the same proper physical distance l. Different values of curvature parameter k in Robertson--Walker metric represent different cosmological models, correspondingly, we obtain the different interference phases.

Key words: interference phase, mass neutrino, Robertson--Walker space--time
