Measurement of La-139(n,gamma) cross section at n_TOF. En International Conference on Frontiers in Nuclear Structure, Astrophysics and Reactions (FINUSTAR) (551-553), Kos, (Grecia): American Institute of Physics.0-7354-0323-60094-243X (impreso)1551-7616 (electrónico)https://hdl.handle.net/11441/101294The 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>l=0 = 268 ± 22 eV, <D>l=1 < 250 eV neutron strength functions S0 = (0.79 ± 0.03)×10-4, and S1 = (0.73 ± 0.05)×10-4 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].application/pdf5 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/139 LaNeutron captureLevel densityNeutron strength functionMACSinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.1063/1.2201012
