Simultaneous Measurements of the Beta Neutrino Angular Correlation in Ar Pure Fermi and Pure Gamow-Teller Transitions using Beta-Proton Coincidences
V. Araujo-Escalona, D. Atanasov, X. Fléchard +14
We report first time measurements of the beta-neutrino angular correlation based on the kinetic energy shift of protons emitted in parallel or anti-parallel directions with respect…
Electron shakeoff following the \b{eta}+ decay of 19Ne+ and 35Ar+ trapped ions
X. Fabian, X. Fléchard, B. Pons +16
The electron shakeoff of 19F and 35Cl atoms resulting from the \b{eta}+ decay of 19Ne+ and 35Ar+ ions has been investigated using a Paul trap coupled to a time of flight recoil-ion…
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…
Electron shakeoff following the ?+ decay of trapped 35Ar+ ions
C. Couratin, X. Fabian, B. Fabre +15
The electron shakeoff of Cl atoms resulting from the decay of Ar ions has been investigated using a Paul trap coupled to a recoil-ion spectrometer. The ch…
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…
