[Gate-users] physics process for photonuclear reaction

[정숙영]

Dear GATE users,

 

As I tried to get results from any Actors that can store the information of
particle production, I couldn’t get any of results about neutron.

 

I want to simulate the photon and neutron generation when the only one kind
of high Z material(ex, Pb, Pt, W) bombarded with 20 MeV electron beam. 

 

So far, I found many papers that already calculated neutron flux using
other Monte Calro code such as MCNPX, FLUKA but I failed with GATE.

 

In my opinion, it doesn’t include the physics of photonuclear reaction to
separate neutron from the nucleus directly by high energy photon.

 

I Could you explain what is wrong in my physics setting as below here..?

(I didn’t use hadronic process because that physics is regarding to the
incident hadron.)

 

Thank you in advance.

 

Best regards,

Sookyoung
