    "abstract": "The interaction cross sections for $^A Na + ^{12}C$ reaction are calculated\nusing Glauber model. The continuum Hartree-Bogoliubov theory has been\ngeneralized to treat the odd particle system and take the continuum into\naccount. The theory reproduces the experimental result quite well. The matter\ndistributions from the proton drip line to the neutron drip line in Na isotopes\nhave been systematically studied and presented. The relation between the shell\neffects and the halos has been examined. The tail of the matter distribution\nshows a strong dependence on the shell structure. The neutron N=28 closure\nshell fails to appear due to the coming down of the $2p_{3/2}$ and $2p_{1/2}$.\nThe development of the halo was understood as changes in the occupation in the\nnext shell or the sub-shell close to the continuum limit. The central proton\ndensity is found to be decreasing near the neutron drip line, which is due to\nthe proton-neutron interaction. However the diffuseness of the proton density\ndoes not change for the whole Na isotopes.",
