摘要

本文回顾了在 SSC 射频-IPPE 加速器综合设施上进行的研究成果,这些研究旨在研究中子在重核裂变过程中的延迟中子(DN)发射现象。研究考虑了对核反应堆安全运行至关重要的 DN 宏观特性的实验数据:DN 总产率和 DN 时间参数(DN 相对产率及其前体半衰期)、热中子 235U 裂变的 DN 积分能谱以及在此基础上获得的 DN 8 族能谱。考虑了 DN 时间参数及其协方差矩阵的估算程序。获得的数据与其他作者获得的数据进行了比较。本综述不包括作者们在探测延迟中子的基础上开发的研究中子重核裂变物理方法的著作,以及与所获结果的物理解释有关的著作。本文仅提供了一份简要清单,并附有适当的参考文献。

Investigations in the Field of Delayed Neutron Data for Nuclear Technologies Based on the Accelerator Complex of SSC RF-IPPE

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.
