Based on the weakest bound electron potential model theory, the Rydberg energy levels and quantum defects of , and spectrum series for francium atom are calculated. The calculated results are in excellent agreement with the 74 known experimentally measured levels (the absolute difference is less than 0.03 cm-1) and 58 energy levels for highly excited states are predicted.
