Measurement of the state-specific differential cross section for the H+D2→HD(<i>v</i>′=4, <i>J</i>′=3)+D reaction at a collision energy of 2.2 eV

Abstract

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).
