Given the minimum kinetic energy of an alpha particle in nucleus= 0.01304 Mev or 2.09*10^-15 J compare this to the kinetic energy of an emitted alpha particle (5 MeV or 8.010883 *10-13 J), is it possible the alpha particle could have existed inside the nucleus before it was emitted? please explain why or why not?
