Alto is an infrastructure for experimental nuclear physics in France that comprises both an on-line isotope-separation facility based on the photofission of uranium and a stableion beam facility based on a 14.5-MV tandem accelerator. The isotope-separation on-line section of Alto is dedicated to the production of neutron-rich radioactive ion beams (RIB) from the interaction of the γ-flux induce...

The interaction of short and intense laser pulses with plasmas is a very efficient source of relativistic electrons with tunable properties. In low density plasmas, we observed bunches of electrons up to 200 MeV, accelerated in the wake field of the laser pulse. Less energetic electrons (tens of MeV) have been obtained, albeit with a higher efficiency, during the interaction with a solid target...

Background: Neutron-rich nuclei in the $\mathrm{A}\ensuremath{\approx}140--160$ mass region provide valuable information on nuclear structure such as quadrupole- and octupole-shape coexistence evolution of collectivity. These have also a engineering interest because they contribute to total decay heat after fission burst. The concerning $^{145}\mathrm{La}$ is very limited.Purpose: study low-spi...

A conservative modeling and analysis were attempted to explain the presence of nonradioactive fission-like products with nonnatural isotopic ratios observed in some D2O/Pd electrolysis experiments. The collective deformation of a Pd nucleus by multiphoton E1 resonance absorption in a dynamic PdDx lattice was assumed to induce low-energy photofissions via the selective scission channels within t...
