High-resolution two-photon spectroscopy of a 5 p56 p ←5 p6 transition of xenon
Abstract
We report high-resolution Doppler-free two-photon excitation spectroscopy of Xe from the ground state to the 5 p5(<mml:mmultiscripts>P 3 /2 2 </mml:mmultiscripts>) 6 p <mml:mmultiscripts>[3 /2 ] 2 2 </mml:mmultiscripts> electronic excited state. This is a first step to developing a comagnetometer using polarized 129Xe atoms for planned neutron electric dipole moment measurements at TRIUMF. Narrow linewidth radiation at 252.5 nm produced by a continuous wave laser was built up in an optical cavity to excite the two-photon transition, and the near-infrared emission from the 5 p56 p excited state to the 5 p56 s intermediate electronic state was used to detect the two-photon transition. Hyperfine constants and isotope shift parameters were evaluated and compared with previously reported values. In addition, the detected photon count rate was estimated from the observed intensities.
