Hi all-
        The game is to create excited nuclei and then determine their
spectra by detecting the decay gammas (this description is not exclusive).
        Locally, the exctation is done by colliding nuclei, by passing
beams trhough thin screens, and heaven knows what else.

The main concern of nuclear spectroscopy is to identify and study
energy levels of atomic nuclei. The activation analysis is a practical
application of that subfield of physics. Why should the positron
annihilation be part of it?
