Measurement of the neutron incoherent scattering length of Hg using stored ultracold neutrons

C. Abel, K. Bodek, E. Chanel +35

We present the first direct measurement of the neutron incoherent scattering length of Hg. The measurement was performed with the Ramsey apparatus of the neutron electric…

Achieving ultra-low and -uniform residual magnetic fields in a very large magnetically shielded room for fundamental physics experiments

N. J. Ayres, G. Ban, G. Bison +47

High-precision searches for an electric dipole moment of the neutron (nEDM) require stable and uniform magnetic field environments. We present the recent achievements of degaussing…

Search for an interaction mediated by axion-like particles with ultracold neutrons at the PSI

N. J. Ayres, G. Bison, K. Bodek +44

We report on a search for a new, short-range, spin-dependent interaction using a modified version of the experimental apparatus used to measure the permanent neutron electric dipol…

nEDM experiment at PSI: data-taking strategy and sensitivity of the dataset

C. Abel, N. J. Ayres, G. Ban +40

We report on the strategy used to optimize the sensitivity of our search for a neutron electric dipole moment at the Paul Scherrer Institute. Measurements were made upon ultracold…

Monte Carlo simulations for the optimization and data analysis of experiments with ultracold neutrons

N. J. Ayres, E. Chanel, B. Clement +5

Ultracold neutrons (UCN) with kinetic energies up to 300 neV can be stored in material or magnetic confinements for hundreds of seconds. This makes them a very useful tool for prob…

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…
