[Gate-users] Materials.xlm Lead properties

[Dounia Taleb]

Dear Gaters,

I want to simulate an old gamma camera and study the energy spectrum of 
all  detected photons in SD volumes. The problem is to define the good 
properties for material.xlm as I understood. Could someone help me 
through this step? Or anyone know where I can find the refractive 
index, scintillation yield of Lead?

Thank you in advance.
Dounia.
