The fragmentation of ${}^{14}\mathrm{B}$ and ${}^{15,17,19}\mathrm{C}$ have been obtained through the interaction of these nuclei with a tantalum target nucleus at various energies. The Coulomb dissociation cross section has been analyzed within a direct fragmentation model. The theory of diffraction dissociation and diffraction stripping has been incorporated within the framework of the present model to show the nuclear effect in the process of breakup. The theoretical results have been compared with recent experimental works on these neutron-rich drip line nuclei.
