Unformatted text preview: Determine if you need to darken the room.- Find the Zero Field Transition as explained on p5-4i) of Ref. . You can use the X-Y feature of the scope or just observe the detector output on one channel while monitoring the horizontal sweep on the other.- Once you have optimized the fields, determine the relative light intensity change due to this transition and determine the line width (in mG). Compare to the numbers on p5-5 of . - Do experiment 4B "Low Field Resonances" on p4-6 of . Determine the nuclear spins of 85 Rb and 87 Rb. Then, use the known values of the spins to calibrate the sweep and main coils. - Investigate the quadratic Zeeman effect, experiment 4C on p4-12 of . Compare your data with the prediction from the Briet-Rabi equation. 1 References  "Optical Pumping of Rubidium - Guide to the Experiment", TeachSpin Inc., June 2002. Hardcopy available in lab. 2...
