Antimagnetic rotation band in nuclei: a microscopic description
1State Key Laboratory of Nuclear Physics and Technology, School of Physics, Peking University, Beijing 100871, China.
Antimagnetic rotation (AMR) in atomic nuclei was microscopically investigated for the first time using covariant density functional theory. The study successfully reproduced experimental data for the AMR band in 105Cd, supporting AMR
Area of Science:
- Nuclear Physics
- Quantum Mechanics
- Atomic Spectroscopy
Background:
- Antimagnetic rotation (AMR) is a nuclear structure phenomenon.
- Understanding AMR requires advanced theoretical models.
- Previous investigations lacked full microscopic self-consistency.
Purpose of the Study:
- To investigate antimagnetic rotation (AMR) in atomic nuclei microscopically.
- To apply covariant density functional theory and the tilted axis cranking method to AMR.
- To validate the theoretical framework by comparing with experimental data.
Main Methods:
- Covariant density functional theory (DFT).
- Tilted axis cranking (TAC) method.
- Fully self-consistent and microscopic calculations.
Main Results:
- Successfully reproduced the experimental spectrum of the AMR band in 105Cd.
- Accurately predicted B(E2) values for the observed AMR band.
- Demonstrated the capability of the employed methods to describe AMR phenomena.
Conclusions:
- The study provides the first fully self-consistent, microscopic description of AMR.
- The results strongly suggest that AMR is realized in specific nuclear bands.
- Confirms the validity of covariant DFT and TAC for studying nuclear rotation.

Atomic nuclei have a net nuclear spin, , which can have an integer or half-integer value. In atomic nuclei, the spins of protons are paired against each other but not with neutrons, and vice versa. Consequently, an even number of protons does not contribute to...
