要旨

In a crossed molecular beam study we have measured double differential cross sections for the reaction Li + HF(v = 0) → LiF + H at collision energies ranging from Etr = 88 to 378 meV. With rising Etr the angular distribution of LiF in the center-of-mass frame changes from nearly forward–backward symmetric to preferred forward scattering. The mean relative recoil energy of the products amounts to approximately 50% of the available energy with a slight tendency to decrease with rising Etr. Our findings agree well with results of quasiclassical trajectory calculations based on the potential energy surface of Laganà and co-workers. The calculations suggest that the change of the scattering characteristics is caused by the significant dependence of the differential cross sections on the rotational enery of HF rather than by the transition from a long lived complex to a direct mechanism. The present findings are consistent with the results of an earlier crossed beam study obtained employing significantly different experimental techniques and data analysis procedures (C. H. Becker, P. Casavecchia, P. W. Tiedemann, J. J. Valentini and Y. T. Lee, J. Chem. Phys., 1980, 73, 2833).

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
