Description

    Below are various links to 8892 isotopes for astrophysics applications (capture cross sections, capture rates and MACS).

    Different reaction "model sets" were used: "a model set" represents a combination of 7 TALYS models:

    1. Gamma strength function (values 8 or 9): either Gogny D1M HFB+QRPA, or SMLO
    2. Level density (values 1, 2 or 5): Constant temperature + Fermi gas model, or Back-shifted Fermi gas model, or Microscopic level densities (Skyrme force) from Hilaire's combinatorial tables
    3. JLM microscopic optical model potential or KD optical model (values y or n)
    4. Gamma strength function for M1 (values 3 or 8): Hartree-Fock BCS tables or Gogny D1M HFB+QRPA
    5. Collective enhancement (values y or n): yes or no
    6. Width fluctuation (values 0, 1 or 2): Moldauer model, or Hofmann-Richert-Tepel-Weidenmueller model
    7. Mass model (values 0, 1, 2 or 3): Duflo-Zuker formula, Moeller table, Goriely HFB-Skyrme table, or HFB-Gogny D1M table (except for known masses, where the experimental value is used)

    Each of the set models is named with 7 values, such as "91n3n12" (default TALYS model), or 81n8n12. These values correspond to the ones in the TALYS manual. Quantities are definied such as:



    1) XS (n,g) cross sections: capture cross sections from 0.01 eV to 20 MeV (from the TALYS file xs000000.tot)

    2) < sigma_v >: reaction rates for all temperatures taking into account the thermal population of the target (from the TALYS file astrorate.g)

    3) G(T): normalized partition function (from the TALYS file astrorate.tot)

    4) MACS: Maxwellian Averaged (n,g) Cross Sections
