摘要
The deformed relativistic Hartree theory(DRH)is solved both in coordinate space(DRH-c)and in harmonic oscillator basis(DRH-o).Results obtained from these two methods are compared in details.The DRH-c and DRH-o calculations give similar total binding energies,deformation,level structures and radii for nitrogen iso topes,while their descriptions on the density distributions for drip-line nuclei are very different.The large spatiai istributions of nucleon densities,which is crucial to understand a weakly bound system,can only be obtained by DRH-c calculations.This implies that the DRH theory should be solved in coordinate space in order to describe uclei close to the drip line.
