| 英文摘要 | We derive the exchange currents of pseudoscalar, vector, and scalar mesons from Feynman diagrams, and use them to calculate the magnetic form factors of nucleon and Delta(1232). The magnetic moments and electromagnetic radii are obtained by using those form factors and the parameters determined from the masses of nucleon and Delta(1232). We find the magnetic moments and electromagnetic radii of nucleon and Delta(1232) can be produced very well in the extended Goldstone-Boson-exchange model in which all of pseudoscalar, vector, and scalar meson nonet are included. The magnetic moments of Delta(1232) are closer to experiment values and results from lattice calculation than the results obtained by the model without other mesons except for pion and sigma. |
