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. [...]

Lifetimes of the 41+ states in 62,64Fe and the 11/21− states in 61,63Co and 59Mn were measured at the Grand Accélérateur National d'Ions Lourds (GANIL) facility by using the Advanced Gamma Tracking Array (AGATA) and the large-acceptance variable mode spectrometer (VAMOS++). The states were populated through multinucleon transfer reactions with a U238 beam impinging on a Ni64 target, and lifetimes in the picosecond range were measured by using the recoil distance Doppler shift method.

Pseudospin Symmetry and Microscopic Origin of Shape Coexistence in the $^{78}$Ni Region: A Hint from Lifetime Measurements

Lifetime measurements of excited states of the light $N=52$ isotones $^{88}$Kr, $^{86}$Se, and $^{84}$Ge have been performed, using the recoil distance Doppler shift method and VAMOS and AGATA spectrometers for particle identification and gamma spectroscopy, respectively. The reduced electric quadrupole transition probabilities $B(E2;2^+ \rightarrow 0^+)$ and $B(E2;4^+ \rightarrow 2^+)$ were obtained for the first time for the hard-to-reach $^{84}$Ge. [...]

The NEutron Detector Array, NEDA, will form the next generation neutron detection system that has been designed to be operated in conjunction with γ -ray arrays, such as the tracking-array AGATA, to aid nuclear spectroscopy studies. NEDA has been designed to be a versatile device, with high-detection efficiency, excellent neutron- γ discrimination, and high rate capabilities. [...]

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. [...]

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.
