14 MeV neutron activation analysis of rocks and meteorites.
Fourteen-MeV neutron activation analysis has certain unique advantages for the nondestructive analysis of rocks and meteorites. In this review, the principles of the method are outlined, and the techniques for the precise and accurate analyses are summarized. Some current and future applications are described.

Coincidence counting applied to the activation analysis of meteorites and rocks.
The use of gamma-gamma coincidence spectrometry in the instrumental activation analysis of materials of geochemical interest can offer advantages of improved sensitivity and precision for certain elements over other counting techniques. An introduction to some of the theory and the practical considerations involved in the establishment of gamma-gamma coincidence counting systems is presented. Previous applications of this technique to the activation analysis of meteorites and rocks are reviewed, and some future applications are proposed.
