The creation of electronically excited species by the 193 nm excimer laser photolysis of PC& and PBr, has been studied. In addition to halogen and phosphorus atomic lines, emission is detected from highly excited states of Cl2 and Br2, respectively, formed by a two-photon process. We also observe pr
