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 &l D >1=0 = 268 + /- 22 eV, &l D >l=l &l 250 eV neutron strength functions SO =(0.79 + / - 0.03)x0.0001, and S1 = (0.73 + / - 0.05)x0.0001 and the Maxwellian-averaged capture cross section (MACS). The MACS is particularly useful far the determination of the abundance synthesized by the main component of the s process.
