Abstract：
Very neutron-deficient nuclei are investigated with Woods-Saxon potentials, especially the newly measured A=2Z-1 nucleus ⁶⁵As[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 ¹⁷F and in the ground states of ^26,27,28P are reproduced well, and predictions of proton halos are made for the ground states of ^56,57Cu and ⁶⁵As. 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.
- proton halo ,
- valence proton ,
- quasibound state
