摘 要：In the framework of the Hartree–Fock–Bogoliubov(HFB)approach with Skyrme interactions SLy5+T,SLy5+Tw and several sets of TIJ parametrizations,*** Skyrme interaction parametrizations including the tensor terms,the proton density distribution in ^(34)Si and ^(46)Ar nuclei is calculated with and without the tensor *** is shown that the bubble effect in ^(34)Si does not depend a great deal on the Skyrme parametrization and the proton density distribution in ^(34)Si is hardly influenced by the tensor *** to ^(46)Ar,the SLy5+Tw parametrization favors the formation of the bubble structure due to the inversion between the 2s_(1/2) and 1d_(3/2) orbits(2s_(1/2)–1d_(3/2) inversion).The inversion mechanism induced by the SLy5+Tw interaction is analyzed based on the proton single−particle spectra obtained from the SLy5 and SLy5+Tw interactions as well as the wave functions of the 2s_(1/2) and 1d_(3/2) states.
