Tilastollisena virheen\u00e4 k\u00e4ytin keskihajontaa.

I used the standard deviation as a statistical error. I studied the even-even nuclei of Gd (A=130-180) and Dy (140-182), together with the fission isomers in U-226, U-238, Pu-240 and Cm-242 which were also used in optimization of UNEDF1 and UNEDF2 parameterizations. I compared the calculated binding energies and errors with each other and with the experimental ones. In addition to that, I studied which of the used parameters yield the largest contribution to the statistical error and how much the calculated excitation energies of the fission isomers differ from the\nexperimentally measured values.\n\nThe predictions for the nuclear binding energies given by these parameterizations are similar to the experimental results. However, even with the statistical uncertainty bar included, only few of these results coincided with the experimental ones. The statistical error varies between 0.3 and 1.4 MeV depending on a considered nucleus and parameterization. I obseved that UNEDF0 gives better results for the binding energies of lighter nuclei whereas UNEDF1 and UNEDF2 parameterizations give more exact values for heavier nuclei when comparing results with the experimental data. \n\nThe statistical error of every UNEDF parametrization grows quickly as a function of mass number in neutron rich nuclei. This means that when giving predictions for the binding energies, the more neutron rich nuclei are studied, the larger errors are. There are many common and significant parametres between UNEDF parametrizations which contribute to statistical error. The parameter C_0^\u03c1\u2206\u03c1 has large impact on the error of every\nUNEDF parameterization. In addition, the density dependence of the symmetry energy and the symmetry energy coefficient contribute considerably to the total error budget of UNEDF0 and UNEDF1 parameterizations, and the inverse of the isoscalar effective mass is the common significant contributor to the statistical error of theoretical binding energies of two later parameterizations.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted using Plone Publishing form by Tiia Haverinen (tikrneva) on 2015-08-17 09:31:49.931780.
