Synthesis of Magnetized Heavy Nuclei

Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

We study the properties and mass distributions of ultramagnetized nuclei produced as a result of heavy ion collisions, inside magnetar crust, explosions of type II supernovas, and the merging of neutron stars. For magnetic field strengths ranging from 0.1 to 10 TT, the Zeeman effect results in a linear nuclear magnetic response that can be described using magnetic susceptibility. Binding energies rise correspondingly for nuclei with open shells and fall for nuclei with closed shells. A noticeable increase in the generation of corresponding explosion nucleosynthetic products with antimagic numbers is predicted for nuclei belonging to the iron group and the r-process. The magnetic enhancement of 44Ti isotopes is consistent with results from observations and testifying to the substantial increase in the share of the main titanium isotope (48Ti) in the Galaxy’s chemical composition. An increased number of nuclides with low mass numbers is predicted in the peak of the r-process as a result of magnetic effects.
