Zeeman Effect at Explosive Nuclide Formation

Abstract

Nuclear structure and composition in ultra-strong magnetic fields relevant for heavy-ion collisions, supernovae, andmagnetar crusts are analyzed. For field intensities exceeding 0.1 teratesla (TT) nuclear magnetic response is represented as combined reactivity of valent outer-shell nucleons, exhibits linear regime up to a strength of ~10 TT and exceeds significantly nuclear g factor. The Zeeman effect leads to an increase of binding energies for open shell nuclei and a decrease for closed-shell nuclei. Noticeable enhancement and suppression in a yield of corresponding explosive nucleosynthesis products with antimagic and magic numbers corroborate with observational results.
