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.

磁化重核的合成

摘要

我们研究了由于重离子碰撞、磁星壳内部、II 型超新星爆炸和中子星合并而产生的超磁化核的性质和质量分布。对于 0.1 到 10 TT 的磁场强度，塞曼效应会导致线性核磁响应，可以使用磁化率来描述。对于具有开壳的原子核，结合能相应地上升，对于具有封闭壳的原子核，结合能会相应地下降。对于属于铁族和r 过程的核，预测具有反幻数的相应爆炸核合成产物的产生显着增加。⁴⁴的磁性增强Ti同位素与观测结果一致，并证明主要钛同位素（⁴⁸ Ti）在银河系化学成分中的份额大幅增加。作为磁效应的结果，在r 过程的峰值中预测了具有低质量数的核素数量增加。
