Corrected Launch Speed for a Projectile Motion Laboratory

Justin M. Sanders, Michael W. Boleman

At our university, students in introductory physics classes perform a laboratory exercise to measure the range of a projectile fired at an assigned angle. A set of photogates is used to determine the initial velocity of the projectile (the launch velocity). We …

Nuclear Physics Experiments Below The Coulomb Barrier

Justin M. Sanders, J. R. Morales Cifuentes, R. K. Clark, Floyd D. McDaniel et autres

In 1932, Cockcroft and Walton showed that (p,α) reactions with lithium were possible at energies near 100 keV. We report an undergraduate laboratory experiment with 90 keV protons colliding with a thick lithium target. The experiment allows students to observe the products …

Accelerator-based Experiments For Introductory-level Undergraduates

Justin M. Sanders, Floyd D. McDaniel, Barney L. Doyle

Although accelerator based experiments for undergraduates are often considered only for junior or senior physics majors, introductory students can also benefit from them. Rutherford backscattering and a 12C(p,p)12C elastic scattering resonance can be presented in ways that are well‐suited for students who …

Ionization in fast atom-atom collisions: The influence and scaling behavior of electron-electron and electron-nucleus interactions

Justin M. Sanders, Robert D DuBois, Steven Trent Manson, Sheldon Datz et autres

We report cross sections for ionization of He coincident with electron loss from He, Li, C, O, and Ne projectiles. For He, Li, C, and O projectiles, the cross sections were measured directly, while the Ne cross sections were obtained by transforming …

Electron capture by protons and electron loss from hydrogen atoms in collisions with hydrocarbon and hydrogen molecules in the 60–120 keV energy range

Justin M. Sanders, Shinto Varghese, Chris H. Fleming, G A Soosai

Cross sections for electron capture by 60–120 keV protons and electron loss from 60–120 keV hydrogen atoms in collisions with molecular hydrogen, methane (CH 4 ), acetylene (C 2 H 2 ), ethylene (C 2 H 4 ), ethane (C 2 H …

Undergraduate Research Projects in Atomic Collisions and Gamma-ray Spectroscopy

Justin M. Sanders

Research projects at University of South Alabama, an undergraduate physics department, have employed a 150‐kV Cockcroft‐Walton accelerator for atomic collisions and sodium‐iodide and high‐purity germanium detectors for gamma‐ray studies. The atomic collision experiments dealt with electron capture and electron loss in collisions …
