论文摘要
使用GSI处的片段分离剂（FRS），已系统地测量了72个中子富含中子的核的单个中子和质子拆卸截面。通过考虑敲除过程以及初始状态和最终状态相互作用来描述中子驱动的横截面。但是，质子驱动的横截面明显小于相同计算所预测的。观察到的差异可以解释为由于中子蛋白占主导地位对中的短相关质子的敲除。
Single neutron- and proton-removal cross sections have been systematically measured for 72 medium-mass neutron-rich nuclei around Z=50 and energies around 900A MeV using the FRagment Separator (FRS) at GSI. Neutron-removal cross sections are described by considering the knock-out process together with initial- and final-state interactions. Proton-removal cross sections are, however, significantly smaller than predicted by the same calculations. The observed difference can be explained as due to the knockout of short-correlated protons in neutron-proton dominating pairs.
