54fe(D,P)55fe Single Neutron Transfer Presentation, Matthew Quirin, Raymond Saunders
Physics and Astronomy Presentations
During our summer research at the John D Fox Laboratory, we used the 9 MV Tandem van de Graaff accelerator and the Super Enge Split-Pole Spectrograph to make measurements of the neutron transfer reaction 54Fe(d,p) 55Fe to observe and explore excited states of 55Fe and shell structure beyond the magic number N=28. We have created momentum spectra and angular distribution plots of the protons from the reaction which will be analyzed to determine the angular momentum values of states and single-neutron energies in 55Fe in an effort to better understand nuclear structure.

Computational Techniques For Scattering Amplitudes, Juliano A. Everett
Publications and Research
Scattering amplitudes in quantum field theory can be described as the probability of a scattering process to happen within a high energy particle interaction, as well as a bridge between experimental measurements and the prediction of the theory.
In this research project, we explore the Standard Model of Particle Theory, it’s representation in terms of Feynman diagrams and the algebraic formulas associated with each combination.
Using the FeynArts program as a tool for generating Feynman diagrams, we evaluate the expressions of a set of physical processes, and explain why these techniques become necessary to achieve this goal.

Powers Of Ten: From Meters To Nanometers And Beyond, Rob Snyder
Nanotechnology Teacher Summer Institutes
The goal of this activity is to guide students toward an understanding of nanoscale dimensions by:
-
Making a number of measurements using meter sticks, magnifiers, microscopes and spectrometers so students can make observations and generate their own data.
-
Using scientific notation to compare the measurements they have made with the dimensions of very small structures
