Analysis of production of forward-angle fragments in the 22Ne (40 AMeV) + 9Be reaction

A mechanisms of production of forward-emitted fragments in the 22Ne (40 АMeV) + 9Be reaction are investigated. Inclusive velocity and isotopic distributions of products with 3 ≤ Z ≤ 11 were measured on the fragment separator COMBAS. The contribution of direct processes and dissipative ones is presented. Gaussian fitting functions according to Goldhaber formalism has been used to estimate direct components of fragments velocity distributions. Experimental data have been compared to geometric incomplete fusion model predictions. Incomplete fusion model was the first time applied for light nuclei as in the studied reaction system. Overall agreement of simulations with experiment in description of velocity distributions have been achieved for fragments with atomic number close to the projectile mass and for stable isotopes. Discrepancies for other products are the result of transition from incomplete fusion to direct processes with collisions of clusters in the participant zone

Installation for resonance spectroscopy of radioactive light nuclei

The experimental set-up based on the time-of-flight fragment-separator COMBAS and multi-channel registration system is developed for the studies of exotic light nuclei. Precise correlation method will be used for resonance decay spectroscopy

Break-Up Reactions of 6^{6}Li, 7^{7}Be and 8^{8}B

International audienceSecondary beams (6Li,7Be,8B) obtained by separation of fragmentation products of 15N beam (50 A MeV) impinging on a Be target using COMBAS spectrometer. The secondary products will be detected by a telescope consisting of five Si-detectors (dE) and CsI(Tl) detector (Er). By the dE-E method, the telescope allowed us to achieve unambiguous particle identification originating from incident secondary beams as well as theirs reaction products resulting from reactions with one of Si detectors chosen as the target. Accordingly, break-up reactions of 6Li, 7Be and 8B were studied in this experiment
