Introduction:

    About 86000 records are included in the database and the atomic energy levels are given in cm-1. Energy of ground state is taken to be zero. Part data came from the old version of the SPECTR database created in 1988-95 at Multicharged-Ion Spectra Data Center of State Research Center VNIIFTRI, Russia, In 2003 Prof. X.T. Zeng evaluated all the data by correcting some data and the expressions of configuration.
