Radiative Double Electron Capture By Ions In Collisions With Gas Targets, Charles Taylor Apr 2019

Radiative Double Electron Capture By Ions In Collisions With Gas Targets, Charles Taylor

Honors Theses

Radiative double electron capture (RDEC) is a two-step quantum process where two electrons are captured from the target gas to the projectile ion beam with a simultaneous emission of a single photon. The projectile ion beam was obtained from the tandem Van de Graaff accelerator at Western Michigan University. The projectile beam used is fully and partially ionized fluorine 9+, and 8+ in collision with highly pure nitrogen gas. The objective of the research is to observe RDEC from x ray detection using time to amplitude converters (TACs) that look for coincidences between x rays and particles. The signal from …
