Grandunification.com Home Example: The Artificial Decay of the Lithium Nucleus

The artificial decay of the Lithium nucleus is a good example of the Ball-of-Light Particle Model at the atomic level. It is common knowledge in the scientific community that an atom is composed of a solid nucleus surrounded by electrons. Studies of the nucleus are traditionally performed by accelerating particles and directing them so that a collision takes place with the nucleus. (A common analogy is the "break" in billiards. The Queue ball collides with the other balls, which are organized in a group, and breaks the group apart.) By investigating how the collisions break apart atomic nuclei it is possible to make inferences about both the accelerated particle and the nucleus.

A natural assumption that researchers made was the actual collision is what causes the nucleus to break apart. Imagine their surprise when they performed experiments on the Lithium nucleus and discovered that the nucleus would decay even without a collision taking place! In 1933 Rausch von Traubenberg and Döpel investigated Lithium with protons and realized the proton could cause the Lithium nucleus to decay when passing the nucleus far outside of the nucleus! How is this possible?

Traditional theory treats the proton not as a particle but as a wave. When the proton wave passes the Lithium nucleus there is a small probability that the proton wave penetrates into the interior of the Lithium nucleus and, somehow, causes the nucleus to become unstable and split into two alpha particles.

For me, a favorite part of the traditional theory is critical here. In order to explain how the supposed parts of the atomic nucleus -- i.e., protons and neutrons -- are held together in such a way as to resist the electrostatic repulsion of protons, a strong nuclear force is proposed. Furthermore, this force has a "well-like" or "crater-like" pattern.

Inside the radius of the atomic nuclei, the particle is very harmonic. It would take quite a bit of energy to break the core into protons and neutrons. This amount of energy needed to break apart the nucleus is represented by the increased height of the rim of the well at the radius of the atomic nuclei. Outside of this radius the well does not drop off immediately. This slope is a graphical depiction of the energy needed by a particle to "penetrate" the nucleus. The part I like best with this theory -- the critical part -- is the motion of particles "within the crater" is described using standing waves!

Another important detail that determines if a particle inside the well can escape is the thickness of the wall of the well at the energy of the particle attempting to escape. It is found that fast moving particles -- e.g., alpha particles in the case of Lithium -- have a much greater probability to escape than slowing moving particles. Conversely, it is the wall thickness that determines if an impinging particle -- e.g., proton waves in this Lithium example -- have a probability of penetrating the wall.

All of this is described in a slightly different manner using the Ball-of-Light Particle Model. The details are:
