The slow neutron-capture process (the s-process) in nucleosynthesis results in about half of the elements heavier than iron in the universe. Two important reactions in the s-process are Neon-22 (alpha, gamma) and Neon-22 (alpha, neutron), which affect the abundances of elements such as Selenium, Krypton, Rubidium, Strontium, and Zirconium. Researchers recently used two indirect methods to study the reactions.

Aluminum-26 has a quantum state difficult to study in a lab. Scientists instead use ion beam-target interactions to create an environment that adds a neutron to the radioactive isotope Silicon-26 to study excited quantum states in Silicon-27. This approach is possible because of the symmetry between protons and neutrons. This provides rare insight into processes in stars.

While protons populate the nucleus of every atom in the universe, sometimes they can be squeezed into a smaller size and slip out of the nucleus for a romp on their own.
