Measurements of [Delta][ital n]=1 Rydberg transition wavelengths for Be-like Si XI are presented for 1[ital s][sup 2]2[ital s]9[ital l][prime][l arrow]1[ital s][sup 2]2[ital s]10[ital l] and 1[ital s][sup 2]2[ital s]8[ital l][prime][l arrow]1[ital s][sup 2]2[ital s]9[ital l]. The large polarizability of the open core 1[ital s][sup 2]2[ital s] and configuration interaction with nearby 1[ital s][sup 2]2[ital pnl] states yield observable 1-structure that is compared with the polarization model, Multi Configurational Dirac-Fock (MCDF) and Many Body Perturbation Theory (MBPT) calculations. We discussed the high-1 structure of the [ital n]=9--10 transition previously in relation to plasma observations. The first application of MBPT calculations to Be-like Rydberg states was reported with our measurement of the 7[ital I]--8[ital K] transition in S XIII.
