Abstract: The efficiency calibration of a coaxial Ge(Li) detector was established experimentally and fitted to a semi-empirical function based on Mowatt's formula. The good agreement obtained in the relative efficiency curve (2–3%) within the energy range 50–1300 keV shows that a development of Mowatt's formula is possible for coaxial devices. The same function, with some simplifications, was fitted to the experimental efficiencies measured for a planar Si(Li) detector in the energy range 8–60 keV. For the Ge(Li) detector the IAEA set of calibrated sources was used for absolute efficiency determinations and another set (75Se, 133Ba, 226Ra, 56Co) for the relative efficiency measurements. Both the IAEA set and a new one named “Variable energy X-ray sources” which provides a fixed geometry, were used for the Si(Li) detector measurements. The semi-empirical fit used enables the determination of the physical parameters of each detector which are then compared with the values predicted by Paradellis and Hontzeas.
