Doesn't the pion decay occur instantaneously. In that the tunneling of the alpha particle, from within the strong force's expressed radius to outside the strong force's expressed radius, takes no time at all...the alpha particle then decays within the radius of its wavelength, radiating out as the weak force (radiation)?
