• Click on a "Nuclear data" button to display properties of isotopes with a half-life exceeding 10 minutes (3 minutes for Fr).
• Click on a "Hyperfine constant A" button to display the values of magnetic-dipole hyperfine constants A (in MHz) complied from published papers.
• If the atom/ion has metastable states a "Metastable state properties" button will show with a list of metastable states. Click on the button to display the data for dominant electric quadrupole (E2) and magnetic dipole (M1) transitions, lifetimes, and quadrupole moments.
• Click on a "Ref" button to display the sources of the data.
• Click on the "Print" button to print the tables you see on the screen.

Isotopes with half life more than 3 minutes are listed Fr, more than 10 minutes for all other cases.
