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…

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…

A measurement of the neutron to 199Hg magnetic moment ratio

S. Afach, C. A. Baker, G. Ban +51

The neutron gyromagnetic ratio has been measured relative to that of the 199Hg atom with an uncertainty of 0.8 ppm. We employed an apparatus where ultracold neutrons and mercury at…

Apparatus for Measurement of the Electric Dipole Moment of the Neutron using a Cohabiting Atomic-Mercury Magnetometer

C. A. Baker, Y. Chibane, M. Chouder +14

A description is presented of apparatus used to carry out an experimental search for an electric dipole moment of the neutron, at the Institut Laue-Langevin (ILL), Grenoble. The ex…
