I don't think there is much difference. Ionization potential is an older term, and is measured in electron volts.

Explanation:

The (1st) ionization energy is the energy associated with the formation of 1 mole of negative ions from 1 mole (gaseous) atoms, and 1 mol of (gaseous) electrons.

#M(g) rarr M^(+)(g) + e^-# #DeltaH# #=# #"Ionization energy"#

The ionization potential is this energy measured in electron volts. #1# #eV# #=# #96.485# #kJ*mol^-1#.
