New measurements of the neutron electric dipole moment with the Petersburg Nuclear Physics Institute double-chamber electric dipole moment spectrometer
Abstract
This article presents results of measuring the neutron electric dipole moment (EDM) made by the Institut Laue-Langevin (ILL) reactor using the Petersburg Nuclear Physics Institute (PNPI) experimental installation. A double-chamber magnetic resonance spectrometer with prolonged holding of ultracold neutrons has been employed. The results determine the upper limit for EDM neutron quantity equal to |dn| < 5.5 × 10-26e cm at a 90% confidence level.
