Elastic electron scattering on the exotic light nucleus 28S is investigated in the plane wave Born approximation. The variation of the squared form factors of 28S with momentum transfer is compared with that of 32S. It is found that the behavior of the form factors near the second minimum (with a moderate momentum transfer) is sensitive to the alteration of the charge density distribution of halo protons in 28S. This indicates that elastic electron scattering can be a good probe of the structure of proton-halo nuclei.

We investigate the ground state properties of some superheavy nuclei,which may be synthesized in future experiments.Special emphases are placed on the alpha decay energies and half-lives.The alpha decay energies and half-lives from different theoretical models are compared and discussed comprehensively.Through these calculations and comparisons,the optimal superheavy elements to be synthesized in future experiments are proposed theoretically.
