Question gps Co60 decay in solid angle

From: valentina <valentina >

Hi, I am simulating a Co60 source irradiating a target to evaluate the energy deposition the source is coded in a macro with /gps/ion 27 60 and at rest The gps commands min/max theta/phi won't work with the ion as I imagine that the commands apply to the Ni ion and not to the secondary gammas (am I wrong here? otherwise while will it work just fine with gps/particle gamma?)

so I am trying to define the solid angle seen by my target in the stackAction and SteppingAction classes killing the neutrinos (no problem here) and the e-/gamma which wont reach the target

I tried to play with track->GetMomentumDirection() to define the solid angle but without full success : OK with cutting the 'wrong' hemisphere (z-axes), but I am not able to set a condition on the x-y plane.

Do you have any idea? Is there a better way to define a solid angle?

Many thanks

valentina
