[en] The paper discusses the present state of the data on the radiative capture cross-sections of the nuclei of various elements for fast neutrons (with energies above 1 keV). The principal methods of measuring these cross-sections are briefly analysed with a view to evaluating the reliability and accuracy of the information obtained, and also with a view to elucidating possible causes of observed discrepancies. The available experimental data are compared with calculated results, to determine the reliability of such calculations in the case of nuclei for which there are no experimental data, e.g. unstable fission fragments. The authors present their conclusions regarding the most appropriate directions for future work on radiative capture. (author)

Rassmatrivaetsya sostoyanie svedenij po secheniyam radiatsionnogo zakhvata bystrykh nejtronov (s ehnergiyami vyshe 1 keV) na yadrakh razlichnykh ehlementov. Kratko analiziruyutsya osnovnye metody izmereniya ehtikh sechenij s tsel'yu otsenki dostovernosti i tochnosti poluchaemoj informatsii, a takzhe dlya vyyasneniya vozmozhnykh prichin nablyudaemykh raznoglasij. Imeyushchie eksperimental'nye dannye sravnivayutsya s rezul'tatami raschetov sechenij s tsel'yu opredeleniya stepeni uverennosti v pravil'nosti takikh raschetov dlya yader, po kotorym ehksperimental'nye dannye otsutstvuyut (naprimer, dlya nestabil'nykh oskolkov deleniya). V zaklyuchenie delayutsya vyvody o naibolee tselesoobraznykh napravleniyakh dal'nejshikh issledovanij radiatsionnogo zakhvata. (author)Source
