Recent measurements on neutron transfer reactions at deep sub-barrier energies with PRISMA

• lorenzo corradi (INFN - Laboratori Nazionali di Legnaro)

Room: Auditorium Irène Joliot-Curie Recent measurements performed in inverse kinematics at deep sub-barrier energies in the 96Zr+40Ca system will be presented. Target-like recoils have been fully identified with the large solid angle magnetic spectrometer PRISMA. The experimental data for one and two neutron transfer channels have been compared with semiclassical microscopic calculations. For the two neutron transfer channels it is found that the transition to the 0+ state at ~6 MeV, whose wavefunction is dominated by the two neutrons in the 2p_{3/2} shell, is much larger than the ground state one. The comparison with the inclusive data reveals that transitions to states with high multipolarity and non-natural parity are important, suggesting that more complex two-particle correlations have to be taken into account.

Search for X-rays characteristic of element with Z = 120

• Marc Olivier Frégeau (GANIL)

Room: Auditorium Irène Joliot-Curie Super-heavy compound nuclei (Z = 120 and 124) with long fission times (t ≥ 10-18s) have been recently evidenced through experiments [1] applying the crystal blocking technique. This method, because it requires high quality monocrystalline targets, cannot be generalized to define and locate possible islands of stability in the super-heavy region. An alternative approach is to use the fluorescence technique which looks for emission of X-rays characteristic of the compound nucleus formed. The first reaction studied in this way has been 238U+64Ni at 6.6 MeV/nucleon leading to Z=120 compound nuclei. We will discuss this method and its application for the very first time in the super-heavy elements region, and present our latest results and conclusions. [1] M.

Progress on the development and construction of the 50 kW Neutron Converter for Spiral 2 project

• Judilka Bermudez (LNL-INFN)

Room: Auditorium Irène Joliot-Curie LNL-INFN is in charge of the research, development and construction of the 50 kW neutron converter for the Spiral 2 facility for producing radioactive ion beams. In the Spiral 2 project, the deuterons primary beam 40 MeV and 5 mA interacts with a graphite converter for producing a neutron flux of 1x1012 neutrons/s/cm2. The high neutron flux is required for inducing fissions on the UCx fissile target that leads to reach high fission rates and high intensity of the radioactive ion beams. The design of the converter is based on a graphite rotating wheel, that allows the dissipation of the total power of the primary beam, avoiding complex cooling systems. The design had been conceived in such a way to house also the 200 kW converter. A brief summary of the recent developments and state of art on the construction will be presented.
