论文摘要
已获得了包含在核反应堆燃料中的易裂变同位素的新抗毒谱（$^{235} $ u，$^{238} $ u，$^{239} $ u，$^{239} $ u和$^{239} $ u和$^{241} $ pu）。使用了一项组合技术：抗肿瘤光谱的计算及其与上个世纪80年代在Rovno NPP实验中获得的拟合的计算。用这些光谱计算出的裂变同位素的横截面很好地描述了在双回体实验中实验获得的横截面。相同反应堆核心组合物的计算横截面为$σ_{f} =（5.82 \ pm 0.12）\ times10^{ - 43} $ cm $^2 $/fission。这是所有预测之间的最接近结果。获得的光谱与5 MEV观察到的能量区域的实验性光谱相同。
New antineutrino spectra of fissile isotopes ($^{235}$U, $^{238}$U, $^{239}$Pu and $^{241}$Pu) which are containing in a nuclear reactor fuel have been obtained. A combined technique was used: calculation of antineutrino spectra and their fitting to those obtained in the experiment at the Rovno NPP in the 80s of the last century. The cross sections of fissile isotopes calculated with these spectra describe well the cross section obtained experimentally in the Double Chooz experiment. The calculated cross section for the same reactor core composition is $σ_{f} = (5.82 \pm 0.12)\times10^{-43}$ cm$^2$/fission. It is the closest result between all predicted. The obtained spectra have the same "bump" as experimental ones in 5 MeV observed energy region.
