In this article, the B spline technique is employeed to construct finite basis sets for the radial HF equation. MBPT calculation is performed on the radial hyperfine interaction parameters of 11B ground state with such basis sets. The results for the megnetic dipole parametrs are al = 0.7776850, asd = 0.8462827 and asd/al = 1.0882, which is in good agreement with experimental values of 0.778 (2), 0.844 (3) and 1.085. The electric quadrupole parameter is aq = 0.7462691,showing a discrepancy of 6% from the experiment.
