New Analysis of Spin Polarization Data from Jefferson Lab

The ability to control and manipulate spin—whether of electrons, nucleons, or nuclei—has driven advancements in the fields of nuclear physics, particle physics, materials science, and structural biology. Across these fields, there is a common need to create high nuclear spin polarization in a variety of samples, in which Dynamic Nuclear Polarization (DNP) is the preferred technique. The level of nuclear spin polarization of the sample is determined by analyzing the Nuclear Magnetic Resonance (NMR) signal. This work examines polarization data from Jefferson Lab's Run Group C experiments with the goal of identifying small contributions to the signals that have not previously been understood. We will present spin up and spin down polarization analysis of ammonia data and the extraction of different contributions to the signal.
