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…
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…
Dynamic stabilization of the magnetic field surrounding the neutron electric dipole moment spectrometer at the Paul Scherrer Institute
S. Afach, G. Bison, K. Bodek +34
The Surrounding Field Compensation (SFC) system described in this work is installed around the four-layer Mu-metal magnetic shield of the neutron electric dipole moment spectromete…
New constraints on Lorentz invariance violation from the neutron electric dipole moment
I. Altarev, C. A. Baker, G. Ban +40
We propose an original test of Lorentz invariance in the interaction between a particle spin and an electromagnetic field and report on a first measurement using ultracold neutrons…
