Preliminary Results on Neutron Capture of Iodine-127: Toward Investigating Symmetry Violations

Neutron capture cross-section measurements play a key role in understanding nuclear structure and interactions, particularly in exploring p-wave resonances. In this presentation, we report on preliminary results from the analysis of neutron capture on Iodine-127 using the DANCE detector at Los Alamos National Laboratory. These results focus on identifying and analyzing p-wave resonances, which are sensitive to fundamental symmetry violations such as P-even/T-odd interactions.

While the primary goal of this work is to probe potential time-reversal symmetry violations, our current analysis is centered on accurately measuring the gamma-ray emissions following neutron capture. This foundational step is critical for refining cross-section data and preparing for the eventual extraction of resonance parameters. By investigating these p-wave resonances, we lay the groundwork for future studies that will delve deeper into symmetry tests and their implications for nuclear physics.
