Precise Stark-Effect Measurements in the ²Σ-Ground State of CaCl

Wolfgang Ernst, S. Kindt, T. Törring

Research output: Contribution to journalArticlepeer-review


By use of the molecular-beam microwave-optical double-resonance technique the first high-precision Stark-effect measurement of an alkaline-earth monohalide has been performed. Low-field Stark shifts of rotational transitions in the v = 0, X Z state of CaCI exhibited an unexpectedly complicated field dependence which, however, has been shown to be in complete agreement with an exact theoretical calculation.
