Precision cross section measurements of neutron-induced non-elastic gamma production reactions at 14 MeV
Mauricio Ayllon Unzueta, Emanuel Chimanski, Juan Cristhian Luque Gutierrez +4
We present a technique for high-precision absolute measurements of gamma-ray production cross sections (n,xg) induced by 14 MeV neutrons. The technique is based on the Associated P…
Universal gate operations on nuclear spin qubits in an optical tweezer array of Yb atoms
Shuo Ma, Alex P Burgers, Genyue Liu +3
Neutral atom arrays are a rapidly developing platform for quantum science. In this work, we demonstrate a universal set of quantum gate operations on a new type of neutral atom qub…
Space-based Measurements of Neutron Lifetime: Approaches to Resolving the Neutron Lifetime Anomaly
David J. Lawrence, Jack T. Wilson, Patrick N. Peplowski
Free neutrons have a measured lifetime of 880 s, but disagreement between existing laboratory measurements of ~10 s have persisted over many years. This uncertainty has implication…
Measurement of the Free Neutron Lifetime using the Neutron Spectrometer on NASA's Lunar Prospector Mission
Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +2
We use data from the Lunar Prospector Neutron Spectrometer to make the second space-based measurement of the free neutron lifetime finding $τ_n=887 \pm 14_\text{stat}{\:^{+7}_{-3\:…
Space-Based Measurement of the Neutron Lifetime using Data from the Neutron Spectrometer on NASA's MESSENGER Mission
Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +2
We establish the feasibility of measuring the neutron lifetime via an alternative, space-based class of methods, which use neutrons generated by galactic cosmic ray spallation of p…
Chemically-distinct regions within Venus' atmosphere revealed by MESSENGER-measured N2 concentrations
Patrick N. Peplowski, David J. Lawrence, Jack T. Wilson
A defining characteristic of the planet Venus is its thick, CO2-dominated atmosphere. Despite over fifty years of robotic exploration, including thirteen successful atmosphere prob…
Image Reconstruction Techniques in Neutron and Gamma-Ray Spectroscopy: Improving Lunar Prospector Data
Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +4
We present improved resolution maps of the Lunar Prospector Neutron Spectrometer thermal, epithermal and fast neutron data and Gamma-Ray Spectrometer Th-line fluxes via global appl…
Equatorial locations of water on Mars: Improved resolution maps based on Mars Odyssey Neutron Spectrometer data
Jack T. Wilson, Vincent R. Eke, Richard J. Massey +4
We present a map of the near subsurface hydrogen distribution on Mars, based on epithermal neutron data from the Mars Odyssey Neutron Spectrometer. The map's spatial resolution is…
