... (c) After going to an excited state, an atom emits a photon and comes back to the ground state. Suppose there is an uncertainly of about one nanosecond as to when precisely the atom emits the photon. What is the uncertainty in the energy of the emitted photons? (d) A pulse laser emits out pulses of ...

... N there are nB (N ) bound states En < 0, where nB (N ) is in good agreement with eq. (30). The spectrum shows the self-similarity found in the approaches above: scaling the system by a factor e−λ1 , with λ1 = 2π/θ, one recovers the same spectrum for sufficiently small energies, i.e. En+1 (N, g, θ) = ...
