Fluorescence from the primary excited atomic or molecular species at the
wavelength of the exciting radiation (no
relaxation within the excited manifold). This term is also used to designate the radiation emitted
by an atom of the same
wavelength as the longest one capable of exciting its
fluorescence, e.g.
in the case of the hydrogen atom, and
in the case of the mercury atom.
