| The 301.5 nm electric-field-induced quench radiation on a thermal beam of neutral Bi atoms in the metastable 6p3 2P3/2 state for transition to the ground 6p3 4S3/2 state was observed. The measurement of the Stark-enhanced intensity of the radiation as a function of the electric field yields a relationship between the field-free-decay rates for transitions between the metastable 6p3 2P3/2 state and the nearby states that are mixed in by the field. Using the known decay rates, the measurement sets an approximate transition rate of A(6p3 2P3/2 → 6p27s 4P1/2) ≈ (0.50 ± 0.05) s-1. |
