Testing ab initio nuclear structure in neutron-rich nuclei: lifetime measurements of second 2$^+$ states in $^{16}$C and $^{20}$O

To test the predictive power of ab initio nuclear structure theory, the lifetime of the second 2+ state in neutron-rich 20O, tau(2+_2 ) = 150(+80-30) fs, and an estimate for the lifetime of the second 2+ state in 16C have been obtained, for the first time. The results were achieved via a novel Monte Carlo technique that allowed us to measure nuclear state lifetimes in the tens-to-hundreds femtoseconds range, by analyzing the Doppler-shifted gamma-transition line shapes of products of low-energy transfer and deep-inelastic processes in the reaction 18O (7.0 MeV/u) + 181Ta.

Effects of one valence proton on seniority and angular momentum of neutrons in neutron-rich $^{122-131}$Sb$_{51}$ isotopes
/ Biswas, S. (GANIL) ; Lemasson, A. (GANIL) ; Rejmund, M. (GANIL) ; Navin, A. (GANIL) ; Kim, Y.H. (GANIL) ; Michelagnoli, C. (GANIL) ; Stefan, I. (Orsay, IPN) ; Banik, R. (Calcutta, VECC ; HBNI, Mumbai) ; Bednarczyk, P. (Cracow, INP) ; Bhattacharya, S. (Calcutta, VECC ; HBNI, Mumbai) et al.
The neutron-rich $^{122-131}$Sb isotopes were produced as fission fragments in the reaction $^{9}$Be($^{238}$U,~f) with 6.2 MeV/u beam energy. An unique setup, consisting of AGATA, VAMOS++ and EXOGAM detectors, was used which enabled the prompt-delayed gamma-ray ($\gamma$) spectroscopy of fission fragments in the time range of 100 ns - 200 $\mu$s.

Nuclear astrophysics with radioactive ions at FAIR
/ Reifarth, R. ; Altstadt, S. ; Göbel, K. ; Heftrich, T. ; Heil, M. ; Koloczek, A. ; Langer, C. ; Plag, R. ; Pohl, M. ; Sonnabend, K. et al.
The nucleosynthesis of elements beyond iron is dominated by neutron captures in the s and r processes. However, 32 stable, proton-rich isotopes cannot be formed during those processes, because they are shielded from the s-process flow and r-process beta-decay chains. [...]

The unbound nuclei He-9 and He-10 have been produced in proton-knockout reactions from a 280 MeV/u Li-11 beam impinging on a liquid hydrogen target at the ALADIN-LAND setup at GSI. Information on their nuclear structure has been obtained from the relative-energy spectra, He-8 + n and He-8 + 2n, employing reaction models incorporating the structure of Li-11. [...]
