Analytical efficiency curve for coaxial germanium detectors

A new semi-empirical analytical expression of gamma-ray spectrometer efficiency curves has been proposed and a method for their parameters determination has been developed. The complete curve consists of two parts, first being the basic detector characterization curve of low number of parameters and second one being a corrective curve, which adjusts the final results to the required and achievable accuracy.
