An Investigation Into The Energy Levels Of A Free Electron Under The This elegant experiment introduces the double resonance technique, whereby magnetic resonance transitions are detected by optical absorption. circularly polarized light from a rb lamp passes through a cell containing rb vapor. In this prac you will study the “optical pumping” of rubidium (rb) atoms. optical pumping produces a non equilibrium distribution of energy states in a collection of atoms.
Physics 432 Optical Pumping In Rubidium A rubidium high frequency lamp is used as the pumping light source to excite rubidium atoms in a sample cell. the pumping source light is filtered to transmit the d1 rb line and polarizers are used to produce circular polarization. In this experiment, you will use the phenomenon of optical pumping to prepare an atomic gas in a highly polarized state, and also to detect changes in that polarization when you drive the atoms with a resonant radio frequency magnetic eld. Although the experiment is relatively simple to perform, you will need to understand a fair amount of atomic physics and experimental technique to appreciate the signals you witness. This section includes overview and guides for the lab about optical pumping of rubidium vapor.

This section includes overview and guides for the lab about optical pumping of rubidium vapor. This document provides background information on optical pumping and describes the energy level structure of rubidium atoms, which will be used in an experiment to polarize a gas. After discussing some preliminary physics below, we will describe the optical pumping process and how you can observe it by repopulating the energy levels using radio frequency (rf) electromagnetic fields.
