Introduction:        ¡¾More information¡¿

     There are about 860 records of data at present. The data are about electron impact ionization of ions with Z less than 30. On-line calculation and drawing according to the fitting formular have been realized. Part data came from the old version of the SPECTR database created by Multicharged-Ion Spectra Data Center of State Research Center VNIIFTRI in Russia, which were checked by us. More information can be found from the reference.
