[Gate-users] Energy spectrum for opticalphotons

[LLKI JJJY]

Hello every body,

I wish that you doing well,

please I am use  the example of the optical photon, where I need to extract the energy spectrum of the fluorescence photons created inside the crystal by an external beam (140 keV), so in the root output I found the energy spectrum empty,

Please can you help me if it's possible to get the energy spectrum (or wavelength) of the  fluorescence photons inside the crystal ?

So thank you very much at advance
My code bellow :
