  The nuclear resonance parameters and the capture cross section of the neutron
magic isotope 139La has been measured n_TOF. The description of the
experimental apparata is followed by the data analysis procedures. We extracted
the resonance parameters, the main nuclear quantities such as the resonance
integral, the average gamma widths for s- and p-waves, the nuclear level
densities and the neutron strength functions. These results represent a
signifcant improvement over previous data. The deduced Maxwellian-averaged
capture cross sections are important for the interpretation of the most recent
spectroscopic observations in low metallicity stars.
