Description
A new detection channel on atomic ionization for possible neutrino elec-
tromagnetic interactions was identified and studied. Orders of magnitude enhancement
in sensitivities can be expected when the energy transfer to the target is of the atomic-transition scale. Interaction cross-section induced by neutrino magnetic mo-
ments (mu_nu) was evaluated. New upper limit of mu_nu < 1.3×10^{−11} μ_B at 90% confidence level was derived using current data with reactor neutrinos. Potential reaches of future experiments are discussed. Experiments with sub-keV sensitivities can probe mu_nu to 10^{−13} μ_B. Positive observations of mu_nu in this range would imply that neutrinos are Majorana particles. Analysis with new data will be presented.
