Question How to define Scattering length for LaBr3:Ce 

Forum: Processes Involving Optical Photons
Date: 06 Feb, 2013
From: Aleksandar Gostojic <Aleksandar Gostojic>

Dear All,

My group is simulating a LaBr3:Ce scintillator (5x5x1cm) coupled with 64 channel MAPMT. Currently we are monitoring the output signal distribution when using gamma sources like Am or Cs.

Now my 2 questions follow the post by Peter, number 457, in this Category.

1) The authors define attenuation length as combination of scattering length and absorption length. How do I define/code the parameter "scattering length" ?

2) Absorption in geant4 is defined as a process which kills a photon, but in the paper it is said that if a photon is absorbed there is a probability for it to be re-emitted with a slightly lower energy. How can I add this absorption/re-emission mechanism to my simulation ?

Thanks in advance,
