<dt>Description</dt>
<dd>Whenever use is made of thick samples in contact with solid state nuclear track detectors for determination of fission yields, one of the fundamental problems is the evaluation of the effective number of target nuclei which contributes to the fraction of the number of fission events that will be recorded. Besides the peculiarities of the fission case under study (induced or spontaneous fission of heavy nuclei, induced fission of intermediate-mass nuclei, etc), several quantities must be also considered such as the range of fission fragments in both the sample and detector materials, the registration threshold, and the limit angle of incidence for fragment detection. The evaluation of the effective number of target nuclei which contributes to recorded events is based on the evaluation of the effective thickness of the sample. In the present work, a method of evaluating effective thicknesses of thick samples has been developed for binary fission modes, and a cross section formula which takes into account all the necessary corrections due to fragment attenuation effects by a thick target has been deduced for calculating fission yields in induced-fission experiments.</dd>
