Abstract

The measurement of collisional quenching cross sections for the (4p)2 (5s)14P1/2 state of atomic arsenic is reported. The arsenic 4P1/2 state was prepared by excitation from the (4p)34S3/2 ground state with 197.2-nm laser radiation. The fluorescence signal from the (4p)2 (5s)14P1/2 → (4p)32D1/2 transition was monitored at 249.3 nm. Quenching cross sections were obtained for hydrogen, methane, nitrogen, carbon monoxide, and ethylene.
