| Popis: | In this paper, the polarized structure functions of and nuclei have been computed in the second order of the Feynman diagram with and without considering SU(3) symmetry in spin dependence for the partonic distribution of nucleons. For this purpose and at first, the polarized structure functions of the nucleons in nuclei are obtained, using Jacobi polynomials. In this regard, two different and prevalent phenomenological models are used to obtain the required polarized partition distributions. Finally, in deriving the nuclear structure functions, effective nuclear corrections are also imposed. The results show that most of the plots for polarized nuclear longitudinal structure functions, resulted from the used phenomenological model whereas symmetry breaking is taken into account, are more compatible with the available experimental data, there is no considerable difference between the data compatibility with curves of both models for polarized nuclear transverse structure functions. |
