The presence of a neutron halo in C has been demonstrated in several reaction experiments at intermediate energies. In the present study, the dynamical effects of this structure are observed for the first time at Coulomb barrier energies in the C + Pb quasi-elastic scattering at MeV, measured at the HIE-ISOLDE facility, CERN using the high-granularity detector array GLORIA. A combined continuum discretised coupled channels and coupled reaction channels calculation describes the data well and significant coupling effects due both to breakup and single-neutron stripping are identified.

近势垒 15C + 208Pb 弹性散射的强耦合效应


C中中子晕的存在已在几个中间能量的反应实验中得到证明。在本研究中，首次在 MeV 的 C + Pb 准弹性散射中的库仑势垒能量下观察到该结构的动力学效应，这是在 CERN 的 HIE-ISOLDE 设施中使用高粒度探测器阵列 GLORIA 进行测量的。组合的连续离散耦合通道和耦合反应通道计算很好地描述了数据，并且识别了由于破裂和单中子剥离而产生的显着耦合效应。
