| 标题： Properties and transmutation of magnetized heavy nuclei | |
| 摘要： The properties, mass distribution and transmutation of atomic nuclei at strong magnetization arising during heavy ions collisions, type II supernova explosions, neutron star mergers, and in magnetar crusts are considered. For a magnetic field strength range of 0.1 — 10 teratesla the Zeeman effect results in a linear nuclear magnetic response, which can be described by making use of magnetic susceptibility [1]. Accordingly, the binding energies increase for nuclei with an open shell and decrease for nuclei with a closed shell. Noticeable enhancement of a yield of corresponding explosive nucleosynthesis products with anti-magic numbers is predicted for nuclei of the iron group and the r-process. The magnetic enrichment of the 44Ti isotope volume is consistent with the results of direct observations and indicates a significant increase in the fraction of the main titanium isotope 48Ti in the chemical composition of galaxies. Magnetic effects in neutron gamma-capture reactions are analysed. An increase in a volume of nuclides with low mass numbers at the peak of the r-process is predicted to occur due to magnetization. | |
