Description
A new detection channel on atomic ionization for possible neutrino
electromagnetic 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 moments (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.
