Photons can be emitted from atoms by heating them up, where electrons are excited to higher energy states by thermal excitations and they subsequently decay to lower states releasing photons. Would it be possible to use the same method in practice in order to obtain photons as a result of the nuclear transitions? Explain how and why. Which temperature would be needed for that?

In interstellar space near a star there is a region called H II in which highly excited H atoms can be produced in the process e + H = H (highly excited). When a highly excited hydrogen atom makes a transition from n = 109 to n= 108 a photon is emitted. Calculate The wavenumber, in cm and wavelength, in nm, of this radiation. The frequency, in sl, of this radiation. The energy, in Joules, of a single photon of...
