Measurement of the static Stark Shift of the 7s ^2S_1/2 level in atomic cesium
arXiv (Cornell University)(2023)
摘要
We report a new precision measurement of the dc Stark shift of the
6s ^2S_1/2→ 7s^2S_1/2 transition in
atomic cesium-133. Our result is 0.72246 (29)
Hz(V/cm)^-2. This result differs from a previous
measurement of the Stark shift by ∼0.5%. We use this value to recalculate
the magnitude of the reduced dipole matrix elements ⟨7s
||r||7p_j⟩, as well as the vector transition polarizability for the
6s → 7s transition, β̃ = 27.043 (36) a_0^3. This
determination helps resolve a critical discrepancy between two techniques for
determining the vector polarizability.
