Jie Chen: Probing exotic structure using one-nucleon transfer reactions

URL: https://enppreview.tamu.edu/events/pr... ABOUT THE SPEAKER: Jie Chen is now a postdoctoral researcher at Michigan State University and the Facility for Rare Isotope Beams, working in the AT-TPC group. She got her Ph.D. at Peking University in 2016 and had been a postdoctoral researcher in Argonne National Laboratory in the following three years. Her research interest focuses on the study of the single-particle structures of exotic or weakly bound nuclei via transfer reactions using various detection systems. ABSTRACT: Understanding nuclear structure and the nuclear force which drives the underlying changes in orbital spacing are topics of high priority in current nuclear physics research. Tracking single-particle excitations is essential for understanding the nature of weakly bound nuclei and test various nuclear models. There are many experimental methods to study nuclear structure the a very compelling one is one-nucleon transfer reactions. Among light nuclei, Be isotopes provide a great testing ground for various nuclear models, thanks to their small number of valence nucleons and rapidly changing exotic structure. The p-wave normal configuration in low-lying states of 11Be and s-wave intruder configuration in the 0+ states of 12Be will be discussed in light of one-nucleon transfer reactions. Particularly, the 12Be ground state is shown to be dominated by a d-wave component, which is a dramatic change compared to the 11Be ground state, where the s-wave single-particle component governs the formation of the 11Be one- neutron halo. Furthermore, preliminary results of low-lying resonances in 12Be having dominant cross-shell neutron configurations will also be presented along with Gamow shell model (GSM) and Gamow coupled channel (GCC) calculations, which shed light on the three-body structure of 12Be and the effect of coupling to the continuum. The AT-TPC and SOLARIS coupled to reaccelerated beams at FRIB will open ever increasing opportunities for using single-nucleon transfer reactions to probe the single- particle structure of exotic nuclei. Some of these ideas will be discussed based on future experiments prospects.
