PHI-base curates molecular and biological information on genes affecting pathogen-host interactions and some anti-infective targets.
CCC Data Base
Search atomic target data in the CCC Data Base by element and explore its listed atomic records.
About CCC Data Base
The CCC Data Base provides atomic-target scattering data calculated with the convergent close-coupling method. It lists electron-impact, positron-impact, and proton-impact data sets for specific elements and ions, with downloadable zip files and DOI links to related publications.
Coverage is limited to the listed records; molecular targets are held separately. The method is described for atomic and ionic targets well-modelled by one or two valence electrons above a Hartree-Fock core, and inner-core ionisation contributions require separate estimation.
Key features
- Browse electron-impact data for listed atomic and ionic targets
- Access positron-impact data for listed elements and H-like ions
- Access proton-impact data for helium
- Download data sets as zip files with averaged and summed values
- View magnetic sublevel data for helium
- Follow DOI links to source publications for data sets
Best for: Researchers needing CCC excitation and ionisation cross sections for listed atomic targets.
Good for
- Lists dated complete data sets for some targets with ni limits
- Provides DOI links to source publications for data sets
- Covers electron, positron, and proton impact data in one place
Watch out for
- Maintainer notes that the data you want may not be present
- Described scope is targets with one or two valence electrons above a Hartree-Fock core
- Inner-core ionisation can contribute substantially and needs separate Born-based estimation
