The poor accuracy of microscopic models in the prediction of fission observables constrains nuclear industry to rely on semi-empirical models, which in turns need systematic and accurate experimental data on a significant number of observables. In the last decade, large efforts were made in the fission community to improve models of the fission process and of the de-excitation of fission...

233U plays the essential role of the fissile nucleus in the Th-U fuel cycle, which has been proposed as a safer and cleaner alternative to the U-Pu fuel cycle. A particularity of 233U is its small neutron capture cross-section which is about one order of magnitude lower than the fission cross-section on average. Therefore, the accuracy in the measurement of the 233U capture cross-section...

Prompt fission gamma spectra (PFGS) have been recently measured for the 238U(n,f) and 239Pu (n,f) reactions using fast neutrons produced by the LICORNE directional neutron source. The setup consisted of ionization chambers containing the actinides samples and LaBr3 scintillators to measure the coincident prompt fission gamma rays. Prompt fission gamma rays were discriminated from prompt...

The experimental study of the neutron-proton pairing is a challenging task that relies on the strength of the physical observables. Binding energies of N = Z nuclei and rotational properties of finite nuclei are some of the tools used up to now. Despite, their robustness to prove other physical phenomena, they are shown to be insufficient to prove the existence of T =0 pairing collectivity. On...

Yrast (\textit{i.e.} the state with the lower energy for a given spin-partiy) and near-Yrast states were populated in the $^{78}$Ni region by fusion-fission reaction $^{238}$U($^9$Be,X$\gamma$) at GANIL. The prompt $\gamma$-rays were detected by the AGATA array\footnote{S. Akkoyun \textit{et al.}, \textit{AGATA - Advanced GAmma Tracking Array}, NIM A668 (2012) 26-58} and particle...
