Abstract
We discuss how the measurement of the $\bar{\nu}_{e}-e^{-}$ elastic cross section at reactor energies can be used to extract new information on the neutrino oscillation parameters. We also consider the magnetic moment contribution and show how both effects tend to cancel each other when the total cross section is measured. To achieve the separation of each of the effects, experiments capable of measuring angular and energy distributions with respect to the outgoing electron become necessary. The sensitivity of these kind of experiments to magnetic moments, masses and mixings is discussed. We also discuss the possibility of measuring the magnetic moment of $\tau$ neutrinos via $\bar{\nu}_{e}\leftrightarrow \bar{\nu}_{\tau}$ oscillation.
