We calculated hyperfine structure constants of the 5d6s2, 5d26s, 5d3, 5d27s, 5d6s7s, 5d6p2, 4f25d, 4f6s6p, 5d6s6p, 5d26p, 4f5d6s and 4f5d2 levels for 139La I (Z=57). The calculations are based upon the multiconfiguration Hartree-Fock method within the framework of the Breit-Pauli relativistic corrections. Moreover, the results obtained were compared with other available calculations and experiments.
