Radii and Binding Energies of Nuclei from a Model of the pn-pair Interactions | | G.K. Nie
; | | Date: |
13 Aug 2005 | | Subject: | nucl-th | | Affiliation: | Institute of Nuclear Physics, Tashkent, Uzbekistan | | Abstract: | New formulas to calculate the nuclear charge radii and the nuclear binding energies have been derived in the framework of an alpha-cluster model. The particular features of the model are two assumptions that the proton-neutron pair interactions are responsible for adherence between alpha-clusters and that the proton and the neutron from a proton-neutron pair have equal nuclear potentials. These assumptions allow one to determine the charge and Coulomb radii in dependence on the amount of proton-neutron pairs in the nucleus. Unlike the Weizsacker’s formula to calculate nuclear binding energies, in the model the binding energies of alpha-clusters and excess neutrons are estimated separately. The calculated values are in a good agreement with the experimental data. | | Source: | arXiv, nucl-th/0508026 | | Services: | Forum | Review | PDF | Favorites | |
