Web2 de abr. de 2024 · Elements are created by neutron capture during a supernova explosion. During a supernova explosion, vast numbers of high energy neutrons are ejected from the collapsing stellar core. These neutrons are captured by nuclei of heavier elements to produce unstable neutron rich isotopes. These isotopes then decay by beta emission …
