BRAMPDAC Brazilian Atomic, Molecular and Plasma Physics Data Center
BRAMPDAC´s main objectives: • To join as much as possible of the brazilian scientific and technological production in atomic, molecular and plasma physics that may be of interest to nuclear fusion research • To provide a direct, easy and rapid access to these data via the web • To promote, as much as possible, data exchange between the brazilian atomic, molecular and plasma physics communities
International goals • To offer to the nuclear fusion community, in a global scale, a channel for a direct, easy and rapid access to the brazilian scientific production in AMPP • To strenght the worldwide insertion of brazilian AMPP data into the literature.
A broad-interest data center • Spectroscopic data for atoms (energy levels, transition rates) and molecules (energy levels, rotational, vibrational, ionization and dissociation parameters, transition rates) • Collisional data for electron (ion) – atom (molecule) collisions (elastic, rotational, vibrational and electronic excitation, ionization and dissociation cross sections) • Plasma characterization: data on particle densities and local temperatures

BRAMPDAC: present status • More than 1000 electronic data files prepared, catalogued and stored • Extensive and diversified data in the area of electron-molecule collisions • Also diversified (not so extensive) data on electron (ion)-atom collisions and on atomic and molecular spectroscopy • Still a very small amount of plasma physics data.
BRAMPDAC: near-future developments • More agressive “in loco” search for spectroscopy and plasma physics data. • Talks in national meetings on theoretical chemistry and plasma physics to strengthen BRAMPDAC in these areas • BRAMPDAC on the web: not yet available. A site for BRAMPDAC, to be set as a mirror site of IAEA data basis site, is expected for soon.
