Validation of Neutrino Energy Estimation Using Electron Scattering Data
… energy estimation to Jefferson Lab CLAS electron scattering data for 1.1, 2.2 and 4.4 GeV electrons incident on <sup>3</sup>He, <sup>4</sup>He, C and Fe targets. We show that the energy reconstruction from the scattered electron plus proton provides a better description of the beam energy than the …

Exact reconstruction of ocean bottom velocity profiles from monochromatic scattering data
… the solution due either to discretization or to data inaccuracy. These methods are tested on synthetic data obtained from known geoacoustic models of the ocean bottom. Results are found to be very accurate particularly at the top of the sediment layer with resolution of less than the wavelength …

Benchmarking of neutrino energy reconstruction methods using electron-deuterium scattering data
… neutrino-nucleus interactions, and use electron-scattering data with known beam energies to test energy reconstruction methods and interaction models. In particular, we analyze 5 GeV electron-deuteron scattering data measured using the large-acceptance CLAS detector at Jefferson Lab. Despite …

Weighting protein ensembles with Bayesian statistics and small-angle X-ray scattering data
… that agree with pre-existing experimental data. However, as the number of experimental constraints is usually much smaller than the degrees of freedom in the protein, the ensemble construction process is under-determined, meaning there are many different ensembles that agree with a given …

Inclusive and exclusive electron scattering data analysis from Jefferson Lab experiment E12-14-012
… Lab seeks to help remedy this via electron scattering measurements on argon and titanium targets. The experiment collected both inclusive (e,e') and exclusive (e,e'p) data at a wide range of kinematics with the intent to measure the electron-nucleus cross section and thus derive a spectral …

The Structure of Baryon Resonances
… provides a bridge between the infinite-volume scattering data of ex- periment, and finite-volume energy spectra from lattice QCD. By discretising a Hamilto- nian which has been constrained to experimental scattering data, solving the eigenvalue equation for the Hamiltonian provides a …

INELASTIC ELECTRON SCATTERING FROM MOLYBDENUM-92
<p>Differential cross sections for electron scattering from $\sp{92}{\rm Mo}$ have been measured for excitation energies less than 5.1 MeV. The momentum-transfer dependence of these cross sections has been mapped out over a range of 0.5 to 3.1 $fm\sp{-1}$ in the forward direction and 0.8 to 2.9 …

Estimating Gulf of Maine zooplankton distributions using multiple frequency acoustic, video and environmental data
… acoustic models and an integrated set of field data. The accuracy of existing scattering models for fluid-like and elastic-shelled animals is determined by analysis of scattering data from individual animals in a laboratory tank. Results indicate that simple two-ray scattering models are …

A Scattering Theory for Linearised Gravity on the Exterior of the Schwarzschild Black Hole
In this thesis we construct a scattering theory for the linearised Einstein equations on a Schwarzschild background in a double null gauge. We perform this construction in two parts. In Part I, we construct a scattering theory for the spin ±2 Teukolsky equations, which govern certain the extremal, …

Hydrogen Distribution in Metal Hydrides and its Effect on Reactor Physics Calculations
… systems require that neutronmaterial interaction data be accurate, convenient to use, and readily available. When describing these interactions, the corresponding data is highly dependent on factors such as neutron energy, material temperature, and material composition. This work focuses on the …

Measurement of the Deeply Virtual Neutral Pion Electroproduction Cross Section off the Proton at 10.6 GeV using the CLAS12 Detector
… neutral pion production, using 10.6 GeV electron scattering data off a proton target from the CLAS12 experiment in Jefferson Lab Hall B. This measurement is important as exclusive meson production has unique access to the chiral odd Generalized Parton Distributions, and is also a background for …

The analysis of local structural effects in alloys using total scattering and reverse Monte Carlo techniques
… required for the analysis of diffuse scattering, such work has been largely abandoned and hence quantification and assessment of SRO is notably sparse in the literature. The recent development of reverse Monte-Carlo (RMC) methods for the analysis of total scattering data has opened a …

An analysis of pion-nucleon scattering
A phase-shift analysis of elastic pion-nucleon scattering data g from threshold to a pion kinetic energy of 1100 MeV was performed. The resulting partial-wave amplitudes were investigated in the complex energy plane, and the resonance states with their associated zeros and poles were determined. …
