Query: A Proposed Method for Measuring the Electric Dipole Moment of the
  Neutron Using Acceleration in an Electric-Field Gradient and Ultracold
  Neutron Interferometry   The use of an ultracold neutron interferometer incorporating an electrostatic
accelerator having a strong electric field gradient to accelerate neutrons by
their possible electric moments is proposed as a method of measuring the
neutron electric dipole moment. Such electrical acceleration, followed by an
amplifier and a generator of phase difference, could develop relatively large
phase differences and these could be measured by a Mach-Zehnder interferometer.
This method might extend the sensitivity of the measurement by several orders
of magnitude beyond the current limit of 10^{-25} e.cm. Furthermore the
systematic errors in such a measurement could be significantly different from
those of the current EDM experiments.
