中能单核子去除截面的系统学

Systematics of intermediate-energy single-nucleon removal cross sections

J. A. Tostevin, A. Gade

摘要:

现在有大量的实验数据和理论分析,从中子或质子丰富的核的中能束中去除单个核子的反应。在每一次这样的测量中,我们得到了质量为A-1的反应残基的所有束缚终态的总体的包含性截面。这些数据,从不同地区的核图表,并涉及弱束缚和强束缚的核子,与理论预期进行比较。这些计算包括近似处理的反应动力学和壳模型描述的弹丸初始状态,绑定的最终状态的残留物,和单粒子强度计算从他们的重叠功能。结果进行了讨论,在最近的数据,更独家的程函动力学描述的测试,并从更微观的原子核结构模型的输入计算。

英文摘要:

There is now a large and increasing body of experimental data and theoretical analyses for reactions that remove a single nucleon from an intermediate-energy beam of neutron- or proton-rich nuclei. In each such measurement, one obtains the inclusive cross section for the population of all bound final states of the mass A-1 reaction residue. These data, from different regions of the nuclear chart, and that involve weakly- and strongly-bound nucleons, are compared with theoretical expectations. These calculations include an approximate treatment of the reaction dynamics and shell-model descriptions of the projectile initial state, the bound final states of the residues, and the single-particle strengths computed from their overlap functions. The results are discussed in the light of recent data, more exclusive tests of the eikonal dynamical description, and calculations that take input from more microscopic nuclear structure models.
