摘要:

This paper describes experiments performed by undergraduate physics majors to measure the temperature dependence of Doppler-broadening in Rb absorption lines over the interval 290–500 K. We report measurements made with a laser-diode spectrometer on the resolved hyperfine transitions of87Rb(5 2S1/2F=1to5 2P1/2,F=1and 2) near 795 nm, and on the unresolved envelope of the transitions of85Rb(5 2S1/2F=2to5 2P3/2,F=1, 2 and 3) near 780 nm. Agreement between measured and predicted linewidths is very good.
