    "abstract": "The absolute frequency measurement for all of the hyperfine transitions of\n6P1/2 -\u003e 7S1/2 using a self-referencing frequency comb is reported. This\ntransition can be used as a bench marker for the accurate atomic wave function,\nand then improve the calculation of the atomic parity- non-conservation (PNC).\nThe frequency center is precisely determined by saturation spectroscopy\nutilizing a pair of the counter-propagating laser beams intersecting with\natomic beam. Such a Doppler-free profile has been improved to 350 kHz in the\nabsolute frequency measurement. The 7S1/2 state hyperfine splittings have also\nbeen deduced from our results.",
