Example jobcard for High energy photon induced
!************************************************************ -*- fortran -*- !* A JobCard for BUU: !* ================== !* !* This JobCard tries to be a template for all !* "HiEnergy photon+Nucleus" !* collisions. !* Here: on NUCLEON/DEUTERIUM !* -- fermi motion : YES !* -- shadowing : no !* -- propagation : no !* -- decays : YES !* !* This is just a special case of jobHiLepton_N. !* You just give a small, but nonvanishing value for Q2. !* Then nu is the photon energy and the actual value of !* epsilon influences the total cross section in the percent !* region (but may have some influence, whether the code !* may 'reconstruct' the kinematics of a scattered electron. !************************************************************ !************************************************************ !
