Abstract

We present a comprehensive set of vibrationally-resolved cross sections for electron-impact electronic excitation of molecular hydrogen suitable for implementation in collisional-radiative models. The adiabatic-nuclei molecular convergent close-coupling method is used to calculate cross sections for excitation of all bound vibrational levels and dissociative excitation of the B 1ƒ°+u , C 1ƒ®u, EF 1ƒ°+g , BŒ 1ƒ°+u , GK 1ƒ°+g , I 1ƒ®g, J 1ƒ¢g, D 1ƒ®u, H 1ƒ°+g , b 3ƒ°+u , c 3ƒ®u, a 3ƒ°+g , e 3ƒ°+u , d 3ƒ®u, h 3ƒ°+g , g 3ƒ°+g , i 3ƒ®g, and j 3ƒ¢g electronic states from all vi = 0.14 bound vibrational levels of the ground electronic (X 1ƒ°+g ) state. The data set consists of . 5000 cross sections, representing all possible electronic and vibrational transitions between the X 1ƒ°+g state and the n = 2.3 singlet and triplet states (where n refers to the united-atoms-limit principle quantum number). The data are presented in graphical form and provided as both numerical values and analytic fit functions in supplementary data files.
