Find specific reaction cross section in an ENDF file

  1. Jun 23, 2014 #1
    I'm trying to find specific reaction cross section 18O(p,n)18F
    in proton + O-18 TENDL (ENDF format).

    # p + 18O : (p,n) Total
    # Q-value =-2.51902E+00
    # E-threshold= 3.64964E+00
    # # energies = 45
    # E xs
    1.000E+00 0.00000E+00
    2.000E+00 0.00000E+00
    3.000E+00 7.05780E+01
    4.000E+00 1.83053E+02
    5.000E+00 2.56205E+02
    6.000E+00 2.81193E+02
    7.000E+00 3.05196E+02
    8.000E+00 3.10529E+02
    9.000E+00 2.62915E+02
    1.000E+01 1.82168E+02

    It's provided in the link of 18O(p,n)
    ftp://ftp.nrg.eu/pub/www/talys/tendl2013/proton_file/O/018/xs/xs100000.tot
    However, I can not find correspond value in ENDF file.

    Please let me rephrase my the question.
    I'm looking for the cross section of 18O(p,n)18F in the ENDF file of TENDL provided in the link:
    p + 18O : (p,n) ftp://ftp.nrg.eu/pub/www/talys/tendl2013/proton_file/O/018/xs/xs100000.tot
    18O(p,x)18F : Production of 18F ftp://ftp.nrg.eu/pub/www/talys/tendl2013/proton_file/O/018/residual/rp009018.tot
    Which are the same as expected.

    However,the cross section of residual product 9.018000+3 the ENDF file is different as the links above
    ftp://ftp.nrg.eu/pub/www/talys/tendl2013/proton_file/O/018/lib/endf/O018-p.tendl
    https://www.dropbox.com/s/07m9shznsx1jco6/9018.JPG

    I'm very confused about the difference.
    Please advise me.
    Thanks in advance
