The 301.5 nm electric-field-induced quench radiation on a thermal beam of neutral Bi atoms in the metastable 6p^{3} ^{2}P_{3/2} state for transition to the ground 6p^{3} ^{4}S_{3/2} 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 6p^{3} ^{2}P_{3/2} 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(6p^{3} ^{2}P_{3/2} → 6p^{2}7s ^{4}P_{1/2}) ≈ (0.50 ± 0.05) s^{-1}.
