“…Concerning the Feshbach resonances, it is interesting to look at the situation of the excited states which could be possible parents of these resonances. The lowest excited states responsible of the UV spectrum of H 2 S from 4.59 to 8.06 eV [31] are . .…”

“…Also, combined with the distorted-wave approximation, SVIM has been applied to the investigation of electronic excitation in molecules [12][13][14][15][16][17][18] . Besides its capability of treating electron scattering by both neutral and ionic molecular targets, SVIM has very solid theoretical grounds.…”

Recently we h a ve extended our codes based on the Schwinger variational iterative method in order to study elastic electron scattering by non-planar molecules with symmetries reducible to the C 2v point group and also to include a correlation-polarization contribution to the electron-molecule interaction potential. In this work we report the rst application of these newly extended codes to the calculation of cross sections for low-energy elastic scattering of electrons by methane. Di erential, integral and momentum-transfer cross sections were calculated in the 0.1 50 eV incident energy range. Comparison of our results with the extensive a vailable data, both experimental and theoretical, reveals the reliability of our method. Particularly, the Ramsauer minimum at around 0.4 eV and the resonance structure at around 8 eV are well reproduced in our calculations.

“…Recent studies of rotational excitation include H2 (Danby et al 1996), HeH+ and N0+ (Rabadan et al 1998), CO (Randell et al 1996), 0 2 (Mukherjee & Ghosh 1996), H 2 0 (Gianturco et al 1998a), 0 3 (Gianturco et al 1998b), C 0 2 (Gianturco & Stoecklin 1997), and S 0 2 ). Vibrational excitation due to electron collisions has been investigated for H 2 (Lee et al 1996a;Kazanskii 1996;Mazevet et al 1998), HD (Kazanskii 1996), N 2 (Grimm-Bosbach et al 1996;Sweeney & Shyn 1997), OH (Chen & Morgan 1997), CO , and CH 4 (Bundschu et al 1997) while studies of electronic excitation of H 2 (Celiberto et al 1996), CO (Lee et al 1996b;Zubek et al 1997;Zetner et al 1998), CO, C0 2 , and S0 2 (Fomunung et al 1996), N 2 (Gillan et al 1996), NO (Mojarrabi et al 1996), 0 3 (Sweeney & Shyn 1996), H 2 0 (Morgan 1998), H 2 S (Michelin et al 1997), and CH4 and SiH4 (Bettega et al 1998) have been performed.…”

In recognition of its special interdisciplinary character, IAU Commission 14 is linked directly to the Executive Committee. The Commission’s role is to inform the astronomical community of new developments in the diverse fields of research which involve atoms and molecules. Conversely it endeavors to sensitize the research community active in those fields to the specific needs of astronomy, especially concerning basic data and modeling tools. More generally, Commission 14 tries to foster long term relations and collaborations between the two communities and, when necessary, to alert funding authorities to the specific needs of ground and space based astronomy for specific atomic and molecular data. This report is one of the main contributions of Commission 14 to the information of the astronomical community. Several meetings concerned, at least in part, with the need and availability of atomic and molecular data for astrophysics were also sponsored or co-sponsored. In the last triennium, Commission 14 cosponsored IAU Symposium 194 “Astrochemistry: From Molecular Cloud to Planetary Systems” held in Sogwipo (Korea) from Aug. 23 to 27, 1999 and organized by Commission 34. A Joint Discussion: JD1 on “Atomic and Molecular Data for Astrophysics, New Developments, Case Studies and Future Needs” has been planned for the XXIVth IAU General Assembly in Manchester (Aug. 7-19, 2000) and cosponsored by Commissions 15, 16, 29, 34, 36, 40 and 44. Several other Joint Discussions to be held at the Manchester General Assembly are co-sponsored by this commission.
