IDEADB – Innsbruck Dissociative Electron Attachment Database

The Innsbruck Dissociative Electron Attachment (DEA) DataBase node holds relative cross sections for dissociative electron attachment processes of the form: AB + e^– ^–> A^– + B, where AB is a molecule. It hence supports querying by various identifiers for molecules and atoms, such as chemical names, stoichiometric formulae, InChI (-keys) and CAS registry numbers. These identifiers are searched both in products and reactants of the processes. It then returns XSAMS files describing the processes found including numeric values for the relative cross sections of the processes.

Scientific objectives-

DEA processes have several areas of importance, among which are technical applications, biological effects in radiation damage and extra-terrestrial ion chemistry, which makes this node interesting for the astrophysical and astrochemical community. The node is hosted at the University of Innsbruck, Austria and maintained by the group of Paul Scheier. New datasets will be added in the future and contributions are highly welcome.
This database is part of a collaboration that has a created the RADAM portal at [http://radamdb.mbnresearch.com/].
Methodology for data-

Typically, DEA cross section are gathered by means of crossed-beam experiments, where gas-phase molecules are subjected to a controlled beam of energy-selected electrons. The resolution for the energy of the electrons provided differs from experimental setup to experimental setup, but is given for each dataset by means of a reference to a peer-reviewed publication will be given for each cross-section listed in the database.
