When an orbit that acquires an opposite particle looses its weak field, it can no longer hold the upper layer particle. Within the nucleus, therefore, there cannot be any misplaced opposite/negative particles that negates the weak fields.
If we shoot opposite/negative particles into a nucleus, it is possible to destroy the weak fields and collapse the nucleus.
In the case of a positive particle nucleus, negative particles \(e^{-}\), \(g^{-}\) and \(T^{-}\) shot into the nucleus can kill the nucleus.
Kaboom!
