Measurement of the permanent electric dipole moment of the neutron

C. Abel, S. Afach, N. J. Ayres +81

We present the result of an experiment to measure the electric dipole moment (EDM) of the neutron at the Paul Scherrer Institute using Ramsey's method of separated oscillating magn…

Magnetic field uniformity in neutron electric dipole moment experiments

C. Abel, N. Ayres, T. Baker +53

Magnetic field uniformity is of the utmost importance in experiments to measure the electric dipole moment of the neutron. A general parametrization of the magnetic field in terms…

Search for axion-like dark matter through nuclear spin precession in electric and magnetic fields

C. Abel, N. J. Ayres, G. Ban +45

We report on a search for ultra-low-mass axion-like dark matter by analysing the ratio of the spin-precession frequencies of stored ultracold neutrons and Hg atoms for an a…

A Revised Experimental Upper Limit on the Electric Dipole Moment of the Neutron

J. M. Pendlebury, S. Afach, N. J. Ayres +47

We present for the first time a detailed and comprehensive analysis of the experimental results that set the current world sensitivity limit on the magnitude of the electric dipole…

Gravitational Depolarization of Ultracold Neutrons: Comparison with Data

S. Afach, N. J. Ayres, C. A. Baker +47

We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a var…

Measurement of a false electric dipole moment signal from Hg atoms exposed to an inhomogeneous magnetic field

S. Afach, C. A. Baker, G. Ban +46

We report on the measurement of a Larmor frequency shift proportional to the electric-field strength for atoms contained in a volume permeated with aligned magneti…
