Abstract
We report on a study of the broadening of the spectral profiles of Rb D 1 resonance lines in the presence of 3–10 amg of 4 He buffer gas. We observe the width of the line shape to depend linearly on the buffer gas density, the constant of proportionality being Γ=18.6±0.2 GHz amg −1. The precision of this measurement is similar to that achieved by previous experiments. However, the novelty of our approach centers on our implementation of a new tunable diode laser, which is substantially cheaper and easier to operate than lasers used in previous studies. Our technique thus provides a reliable and inexpensive method for measuring the density at the 1% level of polarized targets with sealed glass cells used in nuclear physics experiments.
