Question LHEP_PRECO_HP and Gadolinium 

Keywords: thermal neutron gadolinium physics lists LHEP_PRECO_HP

Hi,

 I'm trying to model the absorption of thermal neutrons by a gadolinium
target.
 I'm using the following lines to define the physics list:

// Physics List

#include "LHEP_PRECO_HP.hh"

 then in main ...

runManager->SetUserInitialization(new LHEP_PRECO_HP);

 The program compiles fine but when I start the simulation I get:

G4NeutronHPNames: Sorry, this material does not come near to any data.
G4NeutronHPNames: Please make sure NeutronHPCrossSections points to the
                  directory, the neutron scattering data are located in.
G4NeutronHPNames: The material was: A=152, Z=64
In case the data sets are at present not available in the neutron data library, please contact Hans-Peter.Wellisch@cern.ch

*** G4Exception: Aborting execution ***

  My environment variables are set and point to the correct directory:

 mario@voabaixo:~/geant4/452/eletronsgd$ cd $NeutronHPCrossSections
 mario@voabaixo:/usr/local/share/G4NDL3.7$

  What is wrong with my program/physics lists/environment variables?
  Thanks,

Mário
