In Ba, we report the first experimental result on highly excited double-Rydberg states Ns(or d)n’p(or d) 22 < N < 34, 40 < n’ < 60) which lie only ~ 0.1 eV below the Ba2+ threshold. These results have been obtained using a selective microwave field ionisation in a double time-of-flight mass spetrometer (D.T.O.E.) which allows the detection of highly excited Rydberg states of the Ba+ ion.
