Consider an alpha particle emission from a 238U nucleus, which emits a 4.2 MeV α particle. The α particle is contained inside the nuclear radius rN≈ 7 x 10-15m. Find the barrier height and the distance the α particle must tunnel and use the square-top potential to calculate the tunneling probability

1: The radioactive decay of heavy nuclei by emissions of an alpha particle is a result of quantum tunneling. Imagine an alpha particle moving around inside a nucleus, approximated by a 1D potential well. When the alpha bounces against the surface of the nucleus, it meets a barrier caused by the attractive nuclear strong force. The dimensions of this barrier vary a lot from one nucleus to another, but as representative numbers you can assume that the barrier’s width is...
