标题： s-process nucleosynthesis of 142^Nd: crisis of the classical model

摘要： 最近关于中子魔力核N = 82的恒星中子俘获截面信息的改进，特别是对于142^Nd的信息，被证明是对s过程核合成模型的一个敏感检验。 尽管这些数据与经典方法不兼容，但它们显著提高了低质量AGB恒星模型预测的观测丰度分布的一致性。 显示英文摘要

摘要： The recently improved information on the stellar neutron capture cross sections of neutron magic nuclei at N = 82, and in particular for 142^Nd, turned out to represent a sensitive test for models of s-process nucleosynthesis. While these data were found to be incompatible with the classical approach, they provide significantly better agreement between the observed abundance distribution and the predictions of models for low mass AGB stars.
