Abstract:We analyze the physical content of structures present in the product differential cross sections (DCSs) of the benchmark F + H 2 (v i , j i , m i ) → FH(v f , j f , m f ) + H reaction, where v, j, and m are the vibrational, rotational, and helicity quantum numbers, respectively, for the initial and final states. We analyze three state-to-state transitions: 000 → 300, 000 → 310, and 000 → 320. Accurate quantum S matrix elements are employed at a translational energy of 0.04088 eV for the Fu−Xu−Zhang potential e… Show more
“…It is known, from many TRI pole computations, 60,[67][68][69][70]83,84,91,92,[99][100][101][102] that an elliptical curve approximately separates the stable and unstable regions. The greendashed ellipses in Fig.…”

“…Some applications of the poles to the angular scattering and integral cross sections are discussed in Refs. [17]- [50]. For a description of the type-II Padé approximation, used by the software, the reader is referred to Refs.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
