Abstract:

The pairing effect and shell structure are two key clues to understand complex structures of atomic nuclei. In this talk I will first give a brief introduction to the nucleon-pair approximation (NPA), which is a truncation scheme of the nuclear shell model from the perspective of correlated nucleon pairs. Then I will talk about some interesting results, both analytical and numerical, based on the NPA as well as other pairing theories.

Biography:

Yi-Yuan Cheng got her B.S. degree in 2009 and Ph.D. degree in 2014 in Peking University, and was a postdoc in Shanghai Jiao Tong University from 2014 to 2017. Since then, she has been a faculty member in East China Normal University. Her research work is mainly on nuclear structure theories, particularly on the pairing theory, the nuclear shell model, mass formulas, and effective interactions. She published more than 40 papers in peer-reviewed physical journals, and has been the Principal Investigator of three successive grants from the National Natural Science Foundation of China in recent years.
