Abstract
  • In AMO (Atomic, Molecular, and Optical) physics, an important part of making precise measurements is obtaining and keeping high phase-space densities of the atoms or molecules being trapped. When working with atoms, nonadiabatic transitions from trapped states to non-trapped states are a key component of trap loss. The theoretical consensus has been that electrostatically trapped molecules, unlike atoms have very low loss rates due to nonadiabatic transitions. However, [1] performed the first experimental study of loss due to nonadiabatic transitions in electrostatically trapped ammonia and claim that they cause significant trap loss. This thesis presents my work on developing a computer simulation to model ammonia in an electrostatic trap and a simple model of trap loss due to nonadiabatic transitions. This thesis will provide background information on the slowing and trapping of molecules and the nonadiabatic transition that causes trap loss.
