New numerical algorithms are devised for high-order, efficient quadrature in domains arising from the intersection of a hyperrectangle and a manifold implicitly defined by level sets. By casting the manifold locally as the graph of a...
Apart from the mesons that the constituent quark model predicts, QCD allows for additional states beyond the quark-antiquark system. Previous experiments have performed partial wave analysis on pion-production data and claim observation...
Measurement of Polarization Observables in γ[over rightarrow]p[over rightarrow] → pπ⁺π⁻ Using Circular Beam and Longitudinal Target Polarization and the CLAS Spectrometer at Jefferson Laboratory
The study of baryon resonances offers a deeper understanding of the strong interaction, since the dynamics and relevant degrees of freedom hidden within them are reflected by the properties of the excited states of baryons. Higher-lying...
Detailed Spectroscopic Study of the High-Spin Structures in ¹⁶⁸,¹⁶⁹,¹⁷⁰,¹⁷¹W and ¹⁹⁶Hg and a Systematic Examination of Nuclear Structure Behavior of Rare-Earth Isotopes in the A≈160−180 Region
High-spin states in the rare-earth nuclei $^{168, 169, 170, 171}$W (Z=74) were produced via fusion evaporation reactions carried out at Argonne National Laboratory (ANL) using the Argonne Tandem Linear Accelerator System (ATLAS). An...
Understanding the theory of how massive stars die is an important astrophysical challenge. An important result in core-collapse supernova (CCSN) theory is that spherically-symmetric, one-dimensional simulations routinely fail to explode, ...
Measurement of Polarization Observables in Vector Meson Photoproduction Using a Transversely-Polarized Frozen-Spin Target and Polarized Photons at CLAS, Jefferson Lab
The study of baryon resonances provides a deeper understanding of the strong interaction because the dynamics and relevant degrees of freedom hidden within them are reflected by the properties of the excited states of baryons. Higher...
We perform a survey of the ( proton K+ K− ), 3 charged track data taken by the CLAS detector for the HyCLAS experiment [1] during the g12 run-period at Jefferson Lab. We aim to study the strong decay amplitudes, partial widths and...
Understanding how massive stars explode as core-collapse supernovae (CCSN) remains an important challenge in stellar evolution theory. When massive stars reach the end of their lives, the central iron core can no longer support the...
The main topic of this dissertation is phase transitions and their unique dynamical behavior. Among the various manifestations of phase transitions, spatial ordering of magnetic moments (spins) as in a ferromagnet is of special interest....
Bosons play an important role in the study of emergent phenomena, such as the appearance of effective degrees of freedom, symmetries, and phase transitions. In this work, we use an ensemble of Hamiltonians with two-body interactions with...
Microscopic nuclear shell model calculations have been advancing in capability over the last 40years. Florida State University's experimental nuclear structure group has participated in this advancement with the introduction of the FSU...
Backbending, Seniority and Pauli Blocking of Pairing Correlations at High Rotational Frequencies in Rapidly Rotating Nuclei: A Systematic Analysis of Er, Yb, Hf and W Isotopes and Nuclear Structure Studies of ¹⁷⁹, ¹⁸⁰W, ¹⁶⁰, ¹⁶¹Gd and ¹⁵⁵Sm
The goal of nuclear structure experiments is to understand how properties of nuclei evolve as a function of key observables such as proton and neutron numbers, deformation, angular momentum and excitation energy, to name a few. In order...
Multi-strange baryons have played an important role in understanding the strong interaction. Despite their importance to advancing quantum chromodynamics (QCD), little is known about such hyperons due to the lack of a strange probe....
Two experiments have been performed at Florida State University using the FSU Compton- Suppressed HPGe Array and associated particle telescope. The first experiment used the 9Be(18O, pnγ) reaction at 35 MeV to study the nuclear structure...
The study of exotic nuclei, and their implication for Astrophysics have become a driving force in low-energy nuclear science, nationally recognized by the construction of the Facility for Rare Isotope Beams (FRIB) laboratory. To maximize...
