A Planck or blackbody distribution of photon energies has a curve
which is essentially zero at high energy, quickly rises to a peak,
and then slowly drops off at lower energies.
Would it be possible -- at least "theoretically" -- to have a
distribution in which the curve rises to a peak and then stays at
about that level all the way down to zero photon energy?
What sort of properties would this radiation have?
