Question how tp define a Na22 positron source 

Forum: Particles

Hey,

I'm working on a positron annihilation spectroscopy simulation. I want to use Na22 as my positron source.

For now I'm using a particle gun that shoots positrons with a Gaussian energy distribution and obviously it is'n accurate enough which leads to my question, Is there a built in Na22 positron source that I can use instead of my particle gun?

Thanks' Or Chen.
