Nuclear matter incompressibility coefficient in relativistic and nonrelativistic microscopic models Academic Article uri icon

abstract

  • We systematically analyze the recent claim that nonrelativistic and relativistic mean field (RMF) based random phase approximation (RPA) calculations for the centroid energy [Formula Presented] of the isoscalar giant monopole resonance yield for the nuclear matter incompressibility coefficient [Formula Presented] values which differ by about [Formula Presented] For an appropriate comparison with the RMF based RPA calculations, we obtain the parameters of the Skyrme force used in the nonrelativistic model by adopting the same procedure as employed in the determination of the NL3 parameter set of the effective Lagrangian used in the RMF model. Our investigation suggests that the discrepancy between the values of [Formula Presented] predicted by the relativistic and nonrelativistic models is significantly less than [Formula Presented]. © 2003 The American Physical Society.
