镜像核简介：质子数和中子数互换的一对原子核称为镜像核，譬如7Li（3个质子4个中子）与7Be（4个质子3个中子）互为镜像核。通过研究镜像核可以了解原子核的同位旋对称性、库仑能、原子核结构等相关信息。该报告对镜像核相关的知识给了非常详细的介绍，是一个非常有用也非常精彩报告。

报告内容包括：

What’s isospin symmetry? 
      Why studying isospin symmetry?
How do we study it?  
      Experimental methods 
      Theoretical methods
What do we learn from the data?
     Few illustrative recent examples

总结与展望

通过对镜像核的研究人们可以了解：
1、Mechanism of nucleon alignment at the backbending
2、Evolution of the radii along a rotational band
3、Importance of the single-particle effects:
    - test interactions and basis
    - information on the configurations
4、Evidence of isospin-non-conserving terms in the nuclear interaction

还可以了解：
Other interesting facets can be, and are being, studied in isobaric multiplets:
- lifetimes and decay probabilities
- magnetic and giromagnetic moments
- isospin mixing …..

These investigations will improve with the advent of intense stable and radioactive beams and the next generation gamma-arrays and ancilaries
Much effort has to be put in the development of theoretical methods
