Abstract In nuclear physics one of the recent discoveries is the existence of exotic nuclei. At the drip line, light exotic nuclei are distinguished by weak binding energies that lead to features of ”exotic” as halos. The halo nuclei have a strong cluster structure and anomalously large radii of matter. Due to their weak binding energy, the remarkable characteristic of the halo nuclei is the long tail of their matter density, so the probability of being excited to continuum states is higher than the stable isotopes and they can break easily. Such nuclei are so short lived that it is difficult to use them as targets. Alternatively, in inverse kinematics, direct reactions can be made. It has been identified that there are two types of halo nuclei, labeled by the type of nucleon forming the halo structure: the neutron and proton halos. While numerous studies were carried out on neutron-halo nuclei, the current knowledge of the effects of proton-halo is still very scarce. It is because, in addition to the nuclear potential, the halo proton has also experienced a Coulomb barrier, and thus the probability of tunneling would be lower than that of a neutron of the same energy for separation. |
