Question Cross section verbose 

Forum: Hadronic Processes

From: George Dedes <George Dedes>

Hi all,

continuing from a slightly older thread.

Running in 9.6 and also 9.5 I get the following:

                                  Hadronic Processes for <neutron>
                                  -----------------------------------
    NeutronInelastic  Models:           NeutronHPInelastic: Emin(GeV)=    0  Emax(GeV)= 0.02
                                            Binary Cascade: Emin(GeV)= 0.019  Emax(GeV)= 20

    NeutronInelastic  Crs sctns:          GheishaInelastic: Emin(GeV)=    0  Emax(GeV)= 100000

            nFission  Models:                   G4LFission: Emin(GeV)= 0.019  Emax(GeV)= 1.79769e+305
                                          NeutronHPFission: Emin(GeV)=    0  Emax(GeV)= 0.02

            nFission  Crs sctns:        NeutronHPFissionXS: Emin(GeV)=    0  Emax(GeV)= 0.02
                                          GheishaFissionXS: Emin(GeV)=    0  Emax(GeV)= 100000

All the limits for the models seem to be as intended, but there is something puzzling me with the xsecs. As I was told in the last thread I discussed that, the top xsec is the one used. So:

- For the Neutron Inelastic, HP model will handle interactions from 0-20MeV and BIC 19MeV-20GeV. In the xsec though, I see only the default Geisha for the whole range. Is really Geisha xsec used in 0-20MeV? As far as I know, the HP uses the HP tabulated xsecs, can it be that Geisha xsecs are used in 0-20MeV in conjuction with the HP model?

- For the fission, again the model limits are as intented, but which xsec will be used in 0-20MeV and which from 19MeV and higher? Is NeutronHPFissionXS overwriting just the 0-20MeV part or the GheishaFissionXS is cancelled completely?
