Boron fission
WebThe atomic structure of boron makes it an effective neutron absorber. In particular, the 10B isotope, present at around 20% natural abundance, has a high nuclear cross-section and can capture the thermal neutrons that … Cosmic ray spallation, also known as the x-process, is a set of naturally occurring nuclear reactions causing nucleosynthesis; it refers to the formation of chemical elements from the impact of cosmic rays on an object. Cosmic rays are highly energetic charged particles from beyond Earth, ranging from protons, alpha particles, and nuclei of many heavier elements. About 1% of cosmic rays also consist of free electrons.
