论文摘要
中子可以在寻找稀有过程的地下实验中诱导背景事件。在深层实验室中的MEV范围内的中子是在自发的裂变过程和($α,n $)反应中产生的。许多计算机代码可用于计算($α,n $)反应的横截面,对各种状态的分支比率和中子产量。我们已经使用Sources4代码来计算中子产量和能源光谱,并从基于Empire2.19/3.2.3和Talys1.9的实验数据和计算中取出的输入横截面和分支比率。我们在这里报告了Sources4计算与用固定能量获得的α梁获得的实验数据的比较。
Neutrons can induce background events in underground experiments looking for rare processes. Neutrons in a MeV range in deep underground laboratories are produced in spontaneous fission processes and ($α,n$) reactions. A number of computer codes are available to calculate cross-sections of ($α,n$) reactions, branching ratios to various states and neutron yields. We have used the SOURCES4 code to calculate neutron yields and energy spectra with input cross-sections and branching ratios taken from experimental data and calculations based on EMPIRE2.19/3.2.3 and TALYS1.9. We report here a comparison of SOURCES4 calculations with experimental data obtained with alpha beams with fixed energies.
