Homework Statement

The diagram shows the decay tracks of a neutron decaying into a proton & electron inside a cloud chamber (the arrows have been added to show the direction of travel). Explain how this diagram was used as evidence for the existence of a third particle the neutrino which has a very small mass & no electro-static charge.

Relevant Equations

I was wondering if anyone could help with this question?

If you have no thoughts on the subject, perhaps you can do some research on the internet and learn about the discovery of the neutrino. Then tell us what you found out and what you think.
