| Summary: | We evaluate uncertainty of giant dipole resonance (GDR) peak energy propagated from the uncertainty of effective interaction parameter. The Monte Carlo calculation of microscopic random phase approximation using randomized parameter sets is performed. Under the condition that correlations between the parameters are considered, the calculated GDR peak energy has an uncertainty of ∼1 MeV irrespective of nuclear mass and is strongly correlated with the parameters, in the present calculations. Our result serves as a guide for a new parametrization of effective interaction. |
