摘要：
We study neutrino spin oscillations in gravitational fields in noncommutative spaces. For the Schwarzschild metric the maximum frequency decreases as the noncommutativity parameter increases. In the case of the Reissner-Nordstrom (RN or Re-No) metric, the maximum frequency of oscillation is a monotonically increasing function of the noncommutativity parameter. In both cases, the frequency of spin oscillations decreases as the distance from the gravitational source grows. We present a phenomenological application of our results. It is also shown that the noncommutativity parameter is bounded as root theta > 0.1 l(P).
