HI and D2 are coexpanded into a vacuum chamber. The photolysis of HI at 212.8 nm initiates the H+D2 reaction. The HD(v=4,J′=3) velocity distribution is determined by analyzing the time‐of‐flight profile of HD+ ions produced by delayed pulsed field ionization of long‐lived Rydberg states. The angular distribution is deduced using the law of cosines (photoloc technique).
