在日本化学研究所放射性同位素束流工厂中，测量了能量约为240 MeV/核子的C靶的精确反应截面。这是首次测量。与球形稳定核的系统学相比，我们观察到了一种增强，特别是在富中子区，这反映了这些同位素的形变。在滴水线附近，压力特别大。用最近发展起来的理论方法分析表明，这种显著的增强应来自于打破壳隙的轨道晕的形成。
Precise reaction cross sections () foron C targets at energies around 240 MeV/nucleon have been measured at the Radioactive Isotope Beam Factory at RIKEN. Theforhave been measured for the first time. An enhancement ofcompared to the systematics for spherical stable nuclei has been observed, especially in the neutron-rich region, which reflects the deformation of those isotopes. In the vicinity of the drip line theforis especially large. It is shown by analysis using a recently developed theoretical method that this prominent enhancement offorshould come from the-orbital halo formation breaking theshell gap.
