Measurement of the thermal neutron macroscopic absorption cross-section on small rock samples. Part of coord. prog. F2 10 05: Nuclear techniques in exploration and exploitation of natural resources: Nuclear bore-hole logging techniques for the determination of rock characteristics

The research in the classification of special techniques needed in the method of absorption cross section measurements applied for rocks of different lithology and the theoretical approach to the application lower than that for typical rock material are presented. The conclusions also contain the proposal of the research for the next year. 13 refs., 7 figs., 8 tabs. (author)
