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…
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…
Neutron to Mirror-Neutron Oscillations in the Presence of Mirror Magnetic Fields
I. Altarev, C. A. Baker, G. Ban +43
We performed ultracold neutron (UCN) storage measurements to search for additional losses due to neutron (n) to mirror-neutron (n') oscillations as a function of an applied magneti…
Test of Lorentz invariance with spin precession of ultracold neutrons
I. Altarev, C. A. Baker, G. Ban +43
A clock comparison experiment, analyzing the ratio of spin precession frequencies of stored ultracold neutrons and Hg atoms is reported. %57 No daily variation of this rati…
