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…
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…
Observation of gravitationally induced vertical striation of polarized ultracold neutrons by spin-echo spectroscopy
S. Afach, N. J. Ayres, G. Ban +45
We describe a spin-echo method for ultracold neutrons (UCNs) confined in a precession chamber and exposed to a magnetic field. We have demonstrated that the ana…
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…
Constraining interactions mediated by axion-like particles with ultracold neutrons
S. Afach, G. Ban, G. Bison +35
We report a new limit on a possible short range spin-dependent interaction from the precise measurement of the ratio of Larmor precession frequencies of stored ultracold neutrons a…
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…
