FORMATION OF THE ENERGY-SPECTRUM OF A MONOENERGETIC X-RAY-LINE AS A RESULT OF INHOMOGENEOUS ABSORPTION IN SEMICONDUCTOR-DETECTORS

It is shown that in the case of inhomogeneous absorption (kd is simila r to 1-30) of monoenergetic radiation in the absence of microinhomogen eities and macroinhomogeneities in a detector a strong distortion is s till possible and it may even result in the appearance of two maxima i n the energy spectrum, particularly in the case of similar values of t he electron and hole range when the efficiency of charge collection is low to moderate (25-90%). An analytic expression is obtained and quan titative criteria are given for finding the ranges of the parameters o f a detector responsible for the distortion in the spectrum. The reaso ns for this distortion in the energy spectrum are identified.
