Joshua Isaacson, William I. Jay, Alessandro Lovato, Pedro A. N. Machado, Noemi Rocco

摘要:

我们提出了一种新的核内级联的方法,它需要作为输入的量子蒙特卡罗核配置,并使用半经典的,基于影响参数的算法modelthe质子和中子在核介质中的传播。我们成功地将我们的模拟与现有的质子碳散射数据和核透明度测量进行了比较。通过分析模拟观测量对进入我们的intrinuclearcascade算法的成分的依赖性,我们提供了一个定量的了解他们的影响。特别强调致力于发挥的作用,核相关性,泡利不相容原理,和interactionprobability分布。

英文摘要:

We propose a novel approach to intranuclear cascades which takes as input quantum MonteCarlo nuclear configurations and uses a semi-classical, impact-parameter based algorithm to modelthe propagation of protons and neutrons in the nuclear medium. We successfully compare oursimulations to available proton-carbon scattering data and nuclear-transparency measurements. Byanalyzing the dependence of the simulated observables upon the ingredients entering our intranuclearcascade algorithm, we provide a quantitative understanding of their impact. Particular emphasisis devoted to the role played by nuclear correlations, the Pauli exclusion principle, and interactionprobability distributions.
