Question fast simulation for neutron

Hello ,everyone!
  I'm sorry for my poor English first!
  I'm studying neutron interract with Si in a small geometry,the cross section of hadronic
interaction are too small.It cost me too much time .
   I want to use "hadronic cross section biasing",but it just used for gamma and eletron.
   Is there anybody who has enhanced the cross section of  hadronic interaction ?
   I'm appreciated for your help!
  A part of my codes are showed bellow:
 G4ProcessManager* pmanager = G4Neutron::Neutron()->GetProcessManager(); 

   // add process 
  G4HadronElasticProcess* thenElasticProcess                               
                         = new G4HadronElasticProcess(); 
   thenElasticProcess->AddDataSet(new G4HadronElasticDataSet);  

   G4LElastic* thenElasticModel = new G4LElastic(); 
   G4NeutronHPElastic* theNeutronHPElasticModel= new G4NeutronHPElastic(); 
   theNeutronHPElasticModel ->SetMaxEnergy(20.*MeV);
