Abstract :
Precision saturation absorption spectroscopy on a vapor cell was performed for 88Sr 1S0 - 3P1 spin-forbidden transition. Various kinds of rare gas were introduced into the cell as buffer gas (BG) and the collision shift due to the BG was detected at ~kHz level. The results and theory to validate the experiment may help to correctly estimate the influence on state-of-the-art lattice clocks whose clock transition 1S0 - 3P1 is similar to the transition investigated here.
