dc.description.abstract	The differential cross sections of the 11B(3He,d)12C reaction leading to formation of the 0+ ground state and the 15.11-MeV 1 +, 16.57-MeV 2−, and 17.23-MeV 1− excited states of 12C are measured at Elab=25 MeV. The analysis of the data is carried out within the coupled-reaction-channels method for the direct proton transfer to the bound and unbound states. The rms radii of the last proton in all states studied are determined. A comparison of the rms radii of the 12B, 12C, and 12N nuclei in the isobaric analog states (IASs) with isospin T=1 determined by different methods allows us to arrive at a conclusion that these nuclei in the 1− excited states at Ex=2.62, 17.23, and 1.80 MeV, respectively, possess one-nucleon (neutron or proton) halo structure. The enlarged radii and a large probability of the last neutron to be outside of the range of the interaction potential are also found for the 2− states of 12B, 12C, and 12N at Ex=1.67, 16.57, and 1.19 MeV, respectively. These IASs also can be regarded as candidates for states with one-nucleon (neutron or proton) halo.	en

K.; Vencelj, M.; Yavor, M. I.; Zhao, J. (American Physical Society (APS), 2021)

Mass measurements of the nuclides 69As, 70,71Se, and 71Br, produced via fragmentation of a 124Xe primary beam at the Fragment Separator (FRS) at GSI, have been performed with the multiple-reflection time-of-flight mass ...
Bootstrap technique to study correlation between neutron skin thickness and the slope of symmetry energy in atomic nuclei

Muir, D.; Pastore, A.; Dobaczewski, Jacek; Barton, C.J. (Jagellonian University, 2018)

We examine the proposed correlation between the neutron skin thickness and the slope of the symmetry energy for two doubly-magic nuclei ( 100Sn and 132Sn) and find that a statistically significant correlation appears to ...
