Abstract
If the magnetic moment of unstable tau neutrinos with the mass of 0(MeV) is in the region of 10-8μB≲ μντ≲ 10-6μB, it is compatible with the present experimental and cosmological bounds. We point out that if the tau neutrino has such a large magnetic moment and can oscillate into a neutrino of another flavor, the results from νe scattering experiment at LAMPF constrain the tau neutrino mixing angles to sin 2 2θeτ≲ 2 × 10-6-2 × 10-2 and sin 2 2θμτ ≲ 10-6-10-2 depending on the magnetic moment value in the allowed region.Keywords
