摘要：

Following 193 nm photodissociation of KI, a three-photon (2 + 1) resonance-enhanced multiphoton ionization (REMPI) technique is employed to probe the nascent I fragment as partitioned in its two lowest fine-structure states. It is found that the quantum yield of the ground state I(5(2)P3/2) amounts to 97 +/- 3%. This result and previous observations indicate that the accompanying partner K atom is predominantly partitioned to the 5(2)P(J) state. while the fragment in the lower states can be negligible.
