269. Structure of 17B from quasi-free (p,pn) reaction

Dr Zaihong Yang

Oral contribution

Nuclear physics has been largely extended to the vicinity of the neutron drip line (the limit of stability) in recent decades where many new intriguing phenomena have been observed. Of particular interest are nuclei with a 2n-halo structure, which generally exhibit a Borromean character without any bound binary subsystems [1].

We have carried out a measurement [2] on the structure of the...

196. Magicity of N=32 in neutron-rich Calcium isotopes studied via (p,pn) reaction

Oral contribution

In nuclei far from stability, close to the neutron dripline, shell evolution is known to give rise to intricate nuclear structure, new magic numbers and halo nuclei. The formation of a new sub-shell closure at N = 32 in the neutron-rich pf-shell nuclei was reported based on a series of observations relying on E(2+) systematics, transition probability and mass measurements. Charge radii...

284. 12C(p,2p)11B Quasi-Free-Scattering in Inverse Kinematics at R³B; For the R3B Collaboration

Tobias Jenegger

28/06/2022, 12:00

Oral contribution

The advanced R³B setup at GSI allows to investigate proton-induced-quasi-free one-nucleon knockout reactions of exotic nuclei in inverse kinematics. This technique gives direct access to the momentum distributions of the scattered off protons in the nucleus before as well as the recoil momentum of the remaining spectator nucleus. In addition to the correlated gamma spectrum it is a powerful...

230. Studies of quasi-free proton knockout reactions with the CALIFA Calorimeter at the R3B/FAIR Setup

Leyla Atar (Technical University Darmstadt)

28/06/2022, 12:20

Oral contribution

A successful and widely used tool for the understanding of the single-particle structure and the role of nucleon-nucleon correlations is proton-induced quasi-free scattering reactions (QFS) at relativistic energies. This technique was successfully applied at the R3B/LAND setup (at GSI in Germany) and has been used with an upgraded setup for the future R3B program at FAIR/GSI. One of the key...

228. The (p,3p) two-proton removal from neutron-rich nuclei

Axel Frotscher (Lawrence Berkeley National Laboratory)

28/06/2022, 12:40

Oral contribution

The knockout of nucleons from nuclei is a powerful tool to investigate nuclear structure. It was observed in several occurrences that different final states in a nucleus are populated when produced from one nucleon knockout (p,2p) or from two nucleon knockout (p,3p). The understanding of the latter could provide a new tool for nuclear spectroscopy.
Two experimental campaigns conducted at...
