Phys. Rev. C 61, 037301 (2000) [4 pages]Isoscalar giant quadrupole resonance state in a relativistic approach with the momentum-dependent self-energiesReceived 14 September 1999; published 14 February 2000 We study the excitation energy of the isoscalar giant quadrupole resonance by the scaling method in the relativistic many-body framework with the momentum dependent parts of the Dirac self-energies arising from the one-pion exchange. It is shown that this momentum dependence enhances the Landau mass significantly and thus suppresses the quadrupole resonance energy while the Dirac effective mass is kept to a reasonable value. © 2000 The American Physical Society URL:
