Abstract：
The complex off-shell single-particle potential in N=Z symmetric nuclear matter is computed with Skyrme interactions. The imaginary parts of the polarization and correlation contributions are calculated analytically and the real parts of them are obtained by means of dispersion relation. The energy dependence of the effective mass is also studied.l
