Question
Which conservation law is violated in nuclear beta decay
if neutrinos are not considered?Solution
In beta decay, an electron (or positron) is emitted from a nucleus. If no neutrino were emitted, the momentum of the system wouldn’t be conserved. The neutrino carries away missing momentum and energy, ensuring momentum and energy conservation. Hence, without neutrinos, linear momentum conservation is violated.
