thank you very much for your answer.
I tried everything like you explained it but I think there still must be a fault somewhere in my macro.
To check if the particles are all going inside the sphere I made a Detector (green Sphere in the pictures) which has the size of the spherical source. I gave the particles a very small energy so they should stop immediately if they have contact with the Material of the detector. I suspected to get a lot of very short trajectories. Especially for the case of mintheta = 0 and maxtheta = 0. But instead I get trajectories which I can't explain.
In the case of mintheta = 0 and maxtheta = 0 they seem to come just from the middle and in the case of mintheta = 0 and maxtheta = 90 it looks like they are coming form one hemisphere.
I attached some pictures and my macro.
Pleas tell me where I make a mistake.
