Development of collisional data base for elementary processes of electron scattering by atoms and molecules

•BEAMDB database maintaining electron/atom-molecule collisional data has been created.•The DB is MySQL, the web server is Nginx and Python application server is Gunicorn.•Only data that have been previously published and formally refereed are included.•Data protocol for exchanging and representing data is in the “xsams” xml format.•BEAMDB becomes a node within the VAMDC consortium and radiation damage RADAM basis. We present a progress report on the development of the Belgrade electron/molecule data base which is hosted by The Institute of Physics, University of Belgrade and The Astronomical Observatory Belgrade. The data base has been developed under the standards of Virtual Atomic Molecular Data Centre (VAMDC) project which provides a common portal for several European data bases that maintain atomic and molecular data. The Belgrade data base (BEAMDB) covers collisional data of electron interactions with atoms and molecules in the form of differential (DCS) and integrated cross sections as well as energy loss spectra. The final goal of BEAMDB becoming both a node within the VAMDC consortium and within the radiation damage RADAM data base has been achieved.
