Improved measurements of the hyperfine structure of 87Rb5P3/2 state
J Ye, S Swartz, P Jungner, John L. Hall
We have constructed two highly stable and reproducible Rb D2 saturated absoption spectrometers at 780 nm, using rf frequency sideband technique and third harmonic dither lockin detection method respectively. We have achieved +or-}3 kHz reproducibility on the offset between these two independent systems. With heterodyne technique, we have measured the hyperfine splittings of the 5P3/2 state and determined its magnetic dipole (A) and electric quadrupole (B) hyperfine constants with a 10-fold reduction in uncertainty.
