Complete collision data set for electrons scattering on molecular hydrogen and its isotopologues: II. Fully vibrationally-resolved electronic excitation of the isotopologues of H2 ([formula omitted

Abstract

We present a comprehensive set of vibrationally-resolved cross sections for electron-impact electronic excitation of the isotopologues of molecular hydrogen (D2, T2, HD, HT, and DT) initially in the ground electronic state. We apply the adiabatic-nuclei molecular convergent close-coupling (MCCC) method to calculate cross sections from threshold to 500 eV for excitation of all bound vibrational levels and dissociative excitation of the B1Σu+, C1Πu, EF1Σg+, B′1Σu+, GK1Σg+, I1Πg, J1Δg, D1Πu, H1Σg+, b3Σu+, c3Πu, a3Σg+, e3Σu+, d3Πu, h3Σg+, g3Σg+, i3Πg, and j3Δg electronic states from all bound vibrational levels of the ground electronic (X1Σg+) state. Including the previously-published MCCC e-H2 cross sections (Scarlett et al., Atom. Data Nucl. Data Tables 137 (2021) 101361) the data set contains cross sections for over 60,000 electronic and vibrational transitions. The cross sections are presented in graphical form and provided as both numerical values and analytic fit functions in supplementary data files. The data can also be downloaded from the MCCC database at mccc-db.org.
