Abstract

Experiments on measuring the energy spectra and time distributions of delayed neutrons are described. The neutrons are produced in ²³⁸U photofission under the action of bremsstrahlung photons in the LUE-8-5 pulsed electron accelerator at the Russian Academy of Sciences’ Institute for Nuclear Research. The kinetic energy of incident electrons is ≈10 MeV. Measurements are made in the intervals between beam pulses. Fast neutrons are registered by a scintillation spectrometer, with identification of background γ quanta according to the shape of the scintillation pulses.

在辐照脉冲之间的时间间隔内，Eγmax≈10 MeV处的238 U的光裂变产生的延迟中子

摘要

描述了测量延迟中子的能谱和时间分布的实验。在俄罗斯科学院核研究所的LUE-8-5脉冲电子加速器中，在hl致辐射光子的作用下，在²³⁸ U光裂变中产生中子。入射电子的动能约为10 MeV。在束脉冲之间的间隔中进行测量。快中子由闪烁光谱仪进行配准，并根据闪烁脉冲的形状识别背景γ量子。
