[Gate-users] 64 Cu positron spectra problem

[Tien-Phong PHAM]

Dear Gate-users,

I’m trying to simulate the energy spectrum of a Cu-64 source using the ion definition in GATE v8.2, but i have a problem with the positron emission spectra. In fact, the energy distribution with my ion source is very different with spectral definition in the low energy region. I mean the energy spectrum of positron is similar to the energy spectrum of electron.

In this case, i just used the « RadioactiveDecay » as physics list

I would like to ask if someone has experience with ion type source can help me.

Many thanks for your help !
