NIST Electron-Impact Ionization Cross Section Database - SRD 107

Data provided by  National Institute of Standards and Technology

This is a database of total ionization cross sections of atoms and molecules by electron impact. The cross sections were calculated using the Binary-Encounter-Bethe (BEB) model, which combines the Mott cross section with the high-incident energy behavior of the Bethe cross section. Selected experimental data are included. Singly differential cross sections are included for H, He, and H2. Electron-impact excitation cross sections are also included for selected atoms.

NIST Observed Interstellar Molecular Microwave Transitions Database - SRD 116

Data provided by  National Institute of Standards and Technology

This database contains critically evaluated transition frequencies for the molecular transitions detected in interstellar and circumstellar clouds reported in the literature through mid-2008. The tabulated transition frequencies are recommended for reference in future astronomical observations in the centimeter and millimeter wavelength regions. The transition frequencies have been selected through a critical examination and analysis of the laboratory spectral data obtained from the literature.
