TL;DR: Underwood et al. as mentioned in this paper used Underwood's work to study the relationship between underwood's method and the YURCHENKO method in the field of physics and astronomy.

TL;DR: In this paper, a fast algorithm is developed for ranking the species in a chemistry set according to their importance to the modeled densities of user-specified species of interest, which can be used to acquire insight into complex chemistry sets for modeling plasma phenomena or for a species-oriented reduction of the given chemistry set.

TL;DR: In this article, rate coefficients for dissociative electron attachment and electron-impact dissociation processes, involving vibrationally excited molecular oxygen, are presented, and analytical fits of the calculated numerical data, useful in the applications, are also provided.

TL;DR: In this article, a new theoretical procedure for studying these collisions using the R-matrix method was developed and tested for the atom-atom collisions described by a Morse potential, and analytical solutions for continuum states of the Morse potential were derived and compared with numerical results computed using an R-Matrix method, where the inner region wavefunctions were obtained using a standard nuclear motion algorithm.

TL;DR: In this paper, cross sections for electron scattering from atomic and molecular iodine were calculated based on the R-matrix (close-coupling) method and the dissociative electron attachment and vibrational excitation cross sections of the iodine molecule were obtained using the local complex potential approximation.
