Polarized Neutron Measurements of the Internal Magnetization of a Ferrimagnet Across its Compensation Temperature
C. D. Hughes, K. N. Lopez, T. Mulkey +15
We present the first polarized neutron transmission image of a model Neel ferrimagnetic material, polycrystalline terbium iron garnet (Tb3Fe5O12, TbIG for short), as it is taken th…
Development of a Modular Current-Mode NaI(Tl) Detector Array for Parity Odd (n,γ) Cross Section Measurements
J. T. Mills, J. G. Otero Munoz, K. Dickerson +26
The Neutron Optics Parity and Time-Reversal Violation Experiment (NOPTREX) Collaboration has developed a modular array of 24 NaI(Tl) detectors to measure parity and time-reversal s…
New Upper Bounds on Exotic Neutron Spin-Electron Spin Interactions via Neutron Spin Rotation Measurements in a Compensated Ferrimagnet
T. Mulkey, K. N. Lopez, C. D. Hughes +16
We report a search for exotic spin-spin interactions between neutrons and electrons which could signal new physics beyond the Standard Model using slow neutron polarimetric imaging…
The Nab Experiment: A Precision Measurement of Unpolarized Neutron Beta Decay
J. Fry, R. Alarcon, S. Baessler +69
Neutron beta decay is one of the most fundamental processes in nuclear physics and provides sensitive means to uncover the details of the weak interaction. Neutron beta decay can e…
