Thanks for your hints. I've check the Li-7 cross section using Hadr03 example and the macro you provided, and it seems that the cross section in GNDL is correct.

I first check Li-7 with Energy=14.1 MeV:

          hadElastic= 8.7151 mm2/g 	1.0153 barn  
    neutronInelastic= 3.6325 mm2/g 	423.2 mbarn 

                      and Energy = 250 keV
          hadElastic= 76.785 mm2/g 	8.9457 barn  
    neutronInelastic= 0 um2/mg	0 pbarn .

And I also check with Li-6 with energy=14.1 MeV:

          hadElastic= 8.593 mm2/g 	858.3 mbarn 
    neutronInelastic= 5.8589 mm2/g 	585.21 mbarn 

                      and Energy = 246 keV
          hadElastic= 82.544 mm2/g 	8.2447 barn  
    neutronInelastic= 31.566 mm2/g 	3.153 barn 

I obtain these cross section under NeutronHP process:

 Process: hadElastic
        Model:          NeutronHPElastic: 0 eV  ---> 20 MeV
     Cr_sctns:        NeutronHPElasticXS: 0 eV  ---> 20 MeV
     Cr_sctns:            GheishaElastic: 0 eV  ---> 100 TeV

  Process: neutronInelastic
        Model:        NeutronHPInelastic: 0 eV  ---> 20 MeV
     Cr_sctns:      NeutronHPInelasticXS: 0 eV  ---> 20 MeV
     Cr_sctns:          GheishaInelastic: 0 eV  ---> 100 TeV

I 've check these cross section with ENDF/B-VII.0 data library, they are consistent very much.

Any suggestions for the next step?

Best regards, Yuefeng
