Title: Beryllium & Alpha particle Neutron Source confusion
Post by: Plutonium239 on December 29, 2007, 10:32:55 PM

This question has been confusing me for a while, so I hope someone will be able to help out with a decent answer.

If one has an disk-shaped alpha source about the size of the flat head of a thumbtack, and this is directed at a 1-inch diameter sphere of beryllium from a distance of 0mm (meaning contact), with the source directly above the beryllium, is there a specific direction in which the neutrons will be emitted?

Any help would be much obliged.

Thanks,

It'll likely depend on its kinematics. Energy conservation laws apply.

The neutrons will exit isotropically.
