Using the QGSP_BIC_HP, QGSP_BIC to calculate G4_GRAPHIT mass attenuation coefficient for 2MeV neutron, the results like following:
the 1st data from neutron count, and 2nd one from neutron energy.
neutron E(MeV) mass attenuation coefficient PhysicsProcess 1st(cm2/g) 2nd(cm2/g) 2.000000e+00 8.664998e-02 6.588248e-02 QGSP_BIC_HP 2.000000e+00 -6.843797e-02 8.113455e-02 QGSP_BIC
while I found from paper or G4Data, that the mass attenuation coefficient should be 0.14 cm2/g
who can help what's the problem with my calculation?
