Photons of equal energy were incident on two different H-like samples, one containing He ions in n_(1) state and other containing Li^(++) ions in n_(2) state. The incident photons ionises both the samples. If the difference in KE^(8) of the ejected electrons in is 2.55 eV then magnitude of difference in the states of the two ions may be :
