英文摘要Very neutron-deficient nuclei are investigated with Woods-Saxon potentials, especially the newly measured A=2Z1 nucleus As-65 [X.L. Tu et al., Phys. Rev. Lett. 106, 112501 (2011)], where the experimental proton separation energy is obtained as -90(85) keV for the first time. Careful consideration is given to quasibound protons with outgoing Coulomb wave boundary conditions. The observed proton halos in the first excited state of F-17 and in the ground states of (26,) (27,) (28) P are reproduced well, and predictions of proton halos are made for the ground states of Cu-56,Cu- 57 and As-65. The sensitivity of the results to the proton separation energy is discussed in detail, together with the effect of the l=1 centrifugal barrier on proton halos.
