摘要：

Some electroweak models with extended neutral currents, such as those based on the E-6 group, lead to an increase of the <(nu)over bar> - e scattering cross section at energies below 100 keV. We propose to search for the heavy Z' boson contribution in an experiment with a high-activity artificial neutrino source and with a large-mass detector. We present the case for the LAMA experiment with a large NaI(Tl) detector located at the Gran Sasso underground laboratory. The neutrino flux is known to within a one percent accuracy, in contrast to the reactor case and one can reach lower neutrino energies. Both features make our proposed experiment more sensitive to extended gauge models, such as the chi model. For a low enough background the sensitivity to the Z(chi) boson mass would reach 600 GeV for one year running of the experiment. (C) 1999 Elsevier Science B.V.
