A hydrogen - like neutral species in some excited state A, on absorbing a photon of energy 3.066 eV get excited to a new state B. When the electron from state B returns back, photons of a maximum ten different wavelengths can be observed in which some photons are of energy smaller than 3.066 eV, some are of equal energy and only four photons are having energy greater than 3.066 eV. The ionization energy of this atom is |
