论文摘要
采用构型信息熵（CIE）理论来确定富含中子钙的同位素的中子皮肤厚度。 350 MeV/U $^{40-60} $ CA + $^{9} $中的核密度分布和碎片横截面是使用修改的统计磨蚀性能模型计算的。 CIE数量是根据核密度，同位素，质量和电荷分布确定的。使用同位素，质量和电荷分布确定的CIE与弹丸核的中子皮肤厚度确定的CIE之间的线性相关性表明，CIE提供了提取富含中子核的中子皮肤厚度的新方法。
Configurational information entropy (CIE) theory was employed to determine the neutron skin thickness of neutron-rich calcium isotopes. The nuclear density distributions and fragment cross-sections in 350 MeV/u $^{40-60}$Ca + $^{9}$Be projectile fragmentation reactions were calculated using a modified statistical abrasion-ablation model. CIE quantities were determined from the nuclear density, isotopic, mass, and charge distributions. The linear correlations between the CIE determined using the isotopic, mass, and charge distributions and the neutron skin thickness of the projectile nucleus show that CIE provides new methods to extract the neutron skin thickness of neutron-rich nuclei.
