Two ultraviolet photons (250-282 nm) excited atomic bromine, Br(4p(5) 2P(J); J = 1/2, 3/2), to the terms built from the 4p(4)5p electronic configuration. Through visible and infrared (VIS-IR) transitions and/or collisions with ambient gases, the terms transfer to the (2,4)DJ and( 2,4)PJ states in the 4p44d and 4p45s electronic configurations. The vacuum ultraviolet (VUV) emission (125-163 nm) from the 4p(4)4d and 4p(4)5s states to the 4p(5 2)P(J) state was detected. Twenty in 25 allowed two-photon transitions were observed; however, no VUV or VIS-IR emission from the other five transitions was detected. The findings differ from those by the previous reports on the two-photon resonance-enhanced ionization.
