AI总结:

本文通过(p,p'γ)散射实验并结合光核数据归一化,提取了128Te的模型无关核能级密度,发现其介于恒温模型与费米气体模型预期之间,但与Skyrme力微观模型明显偏离。

摘要:

我们利用IFIN-HH的9 MV串列加速器设施上ELI-NP的大体积\labr\\和\cebr\\探测器,通过$(\mathrm{p},\mathrm{p}'γ)$散射实验提取了${}^{128}$Te的原子核能级密度。衰变数据使用光核数据进行了归一化,从而得到了不依赖于恒温模型或费米气体模型内在模型假设的原子核能级密度。推导出的原子核能级密度介于这两个模型的预期之间,但我们观察到它与基于Skyrme力的微观模型存在明显偏离。

英文摘要:

We have extracted the nuclear level density of ${}^{128}$Te from a $(\mathrm{p},\mathrm{p} 'γ)$ scattering experiment using the large-volume \labr\ and \cebr\ detectors from ELI-NP at the 9~MV Tandem facilities at IFIN-HH. The decay data were normalised using photonuclear data, resulting in nuclear level densities without intrinsic model dependencies from the constant temperature or Fermi gas models. The deduced nuclear level density follows in between the expectations from these two models, but we observe a clear divergence from a microscopic model based on the Skyrme force.
