What will be the minimum energy that must be given tona H atom in ground stateso that it canemit an Hgammaphoton if the angular momentum of the system is conserved ?Also , what would be the angular momemtum of Hgamma if the angular momentum of thev system is conserved ?

. H- gamma corresponds to n = 5 to n = 2 transition. Initially the electron is in ground state that’s n = 1.
So, the energy required is E = E5 – E1.
E = (-13.6/52) - (-13.6/12) = 13.06 eV
