Description

This thesis addresses two important and also challenging issues in the research of chemical reaction dynamics of�F+H2 system. One is to probe the reaction resonance and the other is to determine the extent of the breakdown of the Born-Oppenheimer approximation (BOA)�experimentally. The author introduces a state-of-the-art crossed molecular beam-scattering apparatus�using a�hydrogen atom�Rydberg “tagging” time-of-flight method, and presents thorough state-to-state experimental studies to address�the�above issues. The author also describes the observation of the�Feshbach resonance in�the�F+H2 reaction,�a�precise measurement of the differential cross section in�the�F+HD reaction, and validation of a new accurate potential energy surface with spectroscopic accuracy. Moreover, the author determines the reactivity ratio between the ground state F(2P3/2) and the excited state F*(2P1/2) in�the�F+D2 reaction, and exploits the breakdown of BOA in the low collision energy.Typham this is the title: State-to-State Dynamical Research in the F+H2 Reaction System
