Version 2

Welcome to the NIST Multiconfiguration Hartree-Fock and Multiconfiguration Dirac-Hartree-Fock Database. The MCHF/MCDHF database contains collections of transition data from different relativistic theories by different computational methods. For a few collections the Landé gJ factor is provided. Data may be obtained as follows:

 
Click on image to access HF Applet   Selecting an element from the periodic table, then a spectrum, a reference number, and a property of interest. This method displays all data that is available for a selected atomic system.
