Interactions of nucleons: their role in understanding the sun's origin, composition, and source of energy
"This dissertation confirms and demonstrates the utilization of the "Cradle of the Nuclides" in deciphering the Sun. The "Cradle of the Nuclides" is the nuclear energy surface of all 2,850 known nuclides presented as three-dimensional (3-D) plots of mass or atomic number versus charge density …

Analysis of scattered protons in deuteron electrodisintegration with a polarized electron beam and an internal polarized target
… are central to the understanding of how nucleons interact. However, despite decades of research, Quantum Chromodynamics, which governs the interactions of quarks making up nucleons, continues to evade a fully tractable solution. As a result, understanding of the nucleon and how it …

Across the Scales of the Nucleus: Understanding Short Range Correlations from Medium Modification to Probe Independence
… level, SRCs influence the interaction between nucleons. The nucleon-nucleon (NN) interaction, arising from QCD, is crucial in determining nuclear properties. SRCs serve as valuable probes for measuring this NN interaction, as the nucleons within SRCs become effectively decoupled from the rest …

Measurments of Correlated Pair Momentum Distributions in 3He(e,e'pp)n With CLAS
… The kinetic energy distribution for ’fast’ nucleons (p > 250 MeV/c) peaks where two nucleons each have 20% or less and the third or ‘leading’ nucleon carries most of the transferred energy. These fast nucleon pairs (both <em>pp</em> and <em>pn</em>) are back-to-back and carry very little …

Triton Wave Functions Using Realistic Potentials.
… pertaining to the interaction between nucleons, much theoretical effort during the past forty years has been devoted to such systems. Provided that a means is found to predict accurately the eigenvalues and eigenfunctions which result from two-body forces, it is possible that the …

Shining a Light on the Nucleus: Photonuclear Measurements from Correlations to Charmonium
… atomic nucleus is comprised of a collection of nucleons (protons and neutrons), which are bound together by the nucleon-nucleon (NN) interaction that originates from Quantum Chromodynamics (QCD). While most nucleons experience the force from the rest of the nucleus as a single net “mean-field” …

Determing the Properties of Dense Matter: Superconductivity, Bulk Viscosity, and Light Reflection in Compact Stars
… pair quasiparticles from a microscopic theory of nucleons, and calculate the coupling strengths between quasiparticles. We then calculate the structure of magnetic flux tubes, taking into consideration interactions between neutron and proton Cooper pairs. We find that interactions between the …

Medium energy proton induced fission in uranium-238 and bismuth-209
… for the spallation residues, and the number of nucleons lost by the target before and after fission are calculated and compared with experiment for 155 MeV and 1 GeV protons incident on 238U and 209Bi• Some of the model's predictions are in reasonable agreement with the experiment while others …

Single and double polarization observables in the electrodisintegration of the deuteron from BLAST
… mechanisms involved in the interactions between nucleons is one of the fundamental problems in nuclear physics. Over roughly the last 70 years, this question has been approached on many different fronts. We believe that the theory underlying the interaction between nucleons is that between quarks …

Neutrino Transport in Young Neutron Stars
… both absorption and scattering of neutrinos by nucleons. Exact solutions of the transport equation are used, and the effect of neutron - proton interactions on the composition of the matter is allowed for. I consider energy dissipation by neutrinos and show that under many circumstances …

Exploring the limits of a hadronic picture of nuclei through pion and nucleon removal reactions
… state interactions for the ejected pions and nucleons are implemented in a relativistic Glauber eikonal approach. The proposed model can account for the color transparency (CT) phenomenon and short-range correlations (SRC) in the nucleus. Results are presented for kinematics corresponding to …
