One excited state of the sodium atom lies at 25 739.86 cm1 above the ground state, another lies at 50 266.88 cm-1 . Suppose they are connected by a perturbation equivalent in energy to
(a) 100 cm-1 ,
(b) 1000 cm-1 ,
(c) 5000 cm-1 .
Calculate the energies and composition of the states of the perturbed system.
