Possibility to obtain the electron
Is it possible to obtain the electron (or come out) from the nucleus?
Expert
Yes, it is possible. Electron having energy greater than the ordinary atomic electron might come out of the nucleus due to beta decay process. The negative beta is similar to an electron in all respect apart from with difference in the kinetic energy.
