摘要：

The shell-model properties of proton halo states in proton-rich 1s0d shell nuclei are investigated. The most interesting cases appear to be those in P-26,P-27 and S-27. The parallel-momentum distributions of core fragments from proton stripping reactions may provide experimental insight into the structure of the halo states and the role played by the reaction mechanism. The ''generalized Coulomb shift'', defined as the difference between the neutron and proton separation energies for an analogue pair, is shown to vary smoothly as a function of proton-separation energy and provides a good tool for mass extrapolations. The relation between the total interaction cross section and the matter radius is discussed.
