    "abstract": "Ground state properties of neutron rich even-even Be and C nuclei have been\ninvestigated using Relativistic Mean Field approach in co-ordinate space. The\npositions of the neutron drip line are correctly predicted for both the\nelements. The nucleus $^{14}$Be shows a two neutron halo but, contrary to\nexpectation, $^{22}$C does not exhibit any halo structure. In carbon nuclei,\nN=16 comes out as a new magic number. The single particle level ordering\nobserved in stable nuclei is found to be modified in neutron rich Be isotopes.\nElastic partial scattering cross sections for proton scattering in inverse\nkinematics have been calculated using the theoretically obtained densities for\nsome of the nuclei and compared with available experimental data. The total\ncross cross sections for elastic scattering have also been calculated for all\nthe nuclei studied showing a large increase for the halo nucleus $^{14}$Be. The\nnuclei have also been investigated for deformation. The nuclei $^{10}$Be and\n$^{16,18,20}$C are observed to be deformed in their ground state.",
