    "abstract": "The microscopically constrained relativistic mean field theory is used to\ninvestigate the superdeformation for Pb isotopes. The calculations show that\nthere exists a clear superdeformed minimum in the potential energy surfaces\nwith four different interactions NL3, PK1, TM1 and NLSH. The excitation energy,\ndeformation and depth of well in the superdeformed minimum are comparable for\nfour different interactions. Furthermore the trend for the change of the\nsuperdeformed excitation energy with neutron number is correctly reproduced.\nThe calculated two-neutron separation energy in the ground state and\nsuperdeformed minimum together with their differences are in agreement with the\ndata available. The larger energy difference appearing in superdeformed minimum\nreflects a lower average level density at superdeformations for Pb isotopes.",
