Abstract
A review of the results of research at the SSC RF-IPPE accelerator complex, conducted to study the phenomenon of delayed neutron (DN) emission in the fission of heavy nuclei by neutrons, is presented. Experimental data on the macroscopic DN characteristics are considered, which are of paramount importance for safe operation of nuclear reactors: the total DN yield and the DN time parameters (relative yields of DN and half-lives of their precursors), the integral DN energy spectra for the 235U fission by thermal neutrons and the DN 8-group spectra obtained on their basis. The procedure for the estimation of the DN time parameters and their covariance matrices are considered. The data obtained are compared with the data obtained by other authors. This review does not include the works of the authors devoted to developed physical methods for studying the physics of fission of heavy nuclei by neutrons based on detecting delayed neutrons, as well as works related to the physical interpretation of the results obtained. Only a brief list of them is provided with appropriate references.
期刊介绍：
The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
