It is generally believed that neutrino mass hierarchy can be determined at a long baseline experiment, often using accelerator neutrino beams. Reactor neutrino experiments at an intermediate baseline have the capability to distinguish normal or inverted hierarchy. Recently, it has been demonstrated that the mass hierarchy could possibly be identified using Fourier transform to the L/E spectrum if the mixing angle sin(2)(2 theta(13)) > 0.02. In this study, a more sensitive Fourier analysis is introduced. We found that an ideal detector at an intermediate baseline (similar to 60 km) could identify the mass hierarchy for a mixing angle sin(2)(2 theta(13)) > 0.005, without requirements on accurate information of reactor neutrino spectra and the value of Delta m(32)(2).
