Abstract
The capture cross section of the 139La has been measured relative to 197Au standard at n_TOF. We provide here a short description of the experimental apparatus and of the data analysis procedures. The extracted resonance parameters allow to calculate the fundamental nuclear quantities such as average spacing <D > 1=0 = 268 +/- 22 eV, <D > 1=1 <250 eV neutron strength functions S0 = (0.79 +/- 0.03)x 10(4), and S1 = (0.73 +/- 0.05)x10-4 and the Maxwellian-averaged capture cross section (MACS). The MACS is particularly useful for the determination of the abundance synthesized by the main component of the s process [3].
