NIST's Atomic Spectroscopy Data Center mamtains several
online databases on a tomic spectroscopy. These databases
can be accessed via the physics.nlst.gov/PhysReiData web
page. Our main database, Atomic Spectra Database(ASD)
has recently been upgraded to v. -1.1.1, which contains
critically evaluated data for about 174,000spectrallines ,._ .
