We present the first measurement of the $^{47}$K($d,p\gamma$)$^{48}$K transfer reaction, performed in inverse kinematics using a reaccelerated beam of $^{47}$K. [...]

The excited states of unstable $^{20}$O were investigated via $\gamma$-ray spectroscopy following the $^{19}$O$(d,p)^{20}$O reaction at 8 $A$MeV. By exploiting the Doppler Shift Attenuation Method, the lifetime of the 2$^+_2$ and 3$^+_1$ states were firmly established. [...]

Spectroscopic quadrupole moments in Xe124

Background: The Xe isotopic chain with four valence protons above the Z=50 shell closure is an ideal laboratory for the study of the evolution of nuclear deformation. At the N=82 shell closure, Xe136 presents all characteristics of a doubly closed shell nucleus with a spherical shape. [...]

Evidence of Partial Seniority Conservation in the $\pi{g}_{9/2}$ Shell for the $N=50$ Isotones
/ Pérez-Vidal, R M (Valencia U., IFIC ; INFN, Legnaro) ; Gadea, A (Valencia U., IFIC) ; Domingo-Pardo, C (Valencia U., IFIC) ; Gargano, A (INFN, Naples ; Carlos III U., Madrid) ; Valiente-Dobón, J J (INFN, Legnaro) ; Clément, E (GANIL) ; Lemasson, A (GANIL) ; Coraggio, L (INFN, Naples ; Carlos III U., Madrid ; Napoli Seconda U.) ; Siciliano, M (Argonne, PHY) ; Szilner, S (Boskovic Inst., Zagreb) et al.
The reduced transition probabilities for the $4^+_1 \to 2^+_1$ and $2^+_1 \to 0^+_1$ transitions in $^{92}$Mo and $^{94}$Ru and for the $4^+_1 \to 2^+_1$ and $6^+_1 \to 4^+_1$ transitions in $^{90}$Zr have been determined in this experiment making use of a multinucleon transfer reaction. These results have been interpreted on the basis of realistic shell-model calculations in the $f_{5/2}, p_{3/2}, p_{1/2},$ and $g_{9/2}$ proton valence space. [...]

Testing ab initio nuclear structure in neutron-rich nuclei: lifetime measurements of second 2$^+$ states in $^{16}$C and $^{20}$O
/ Ciemala, M. (Cracow, INP) ; Ziliani, S. (Milan U. ; INFN, Milan) ; Crespi, F.C.L. (Milan U. ; INFN, Milan) ; Leoni, S. (Milan U. ; INFN, Milan) ; Fornal, B. (Cracow, INP) ; Maj, A.

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.

$_{36}^{96}$Kr$_{60}$–low-$Z$ boundary of the island of deformation at $N=60$

Prompt γ-ray spectroscopy of the neutron-rich 96Kr, produced in transfer- and fusion-induced fission reactions, has been performed using the combination of the Advanced Gamma Tracking Array and the VAMOSþþspectrometer. A second excited state, assigned to Jπ ¼ 4þ, is observed for the first time, and a previously reported level energy of the first 2þ excited state is confirmed. [...]
