Study of production mechanisms of neutron-rich isotopes in the reaction 22Ne (40MeV/A) + 9Be Summer Students Practice, Flerov Laboratory of Nuclear Reactions, JINR, Dubna 2007-07-06 Summer Students Practice, JINR, Dubna

Summer Students Practice, JINR, Dubna COMBAS Separator Study the reaction mechanisms in the interval of intermediate energies, especially close to the Fermi energy (≈ 38 MeV). Investigation of the particle stability limits Study of the properties of unstable nuclei near the drip-lines Producton of secondary beams of neutron-rich nuclei with 2 ≤ Z ≤ 12 2007-07-06 Summer Students Practice, JINR, Dubna

Summer Students Practice, JINR, Dubna Aim of the project Reproduce experimental velocity distributions of Na, C, and Be isotopes obtained in the reaction 22Ne(40MeV/A) + 9Be(14mg/cm2) using Open LISE ++ Symulator Comparison of experimental data with symulation results 2007-07-06 Summer Students Practice, JINR, Dubna

Results for Be and Na isotopes A.Borowiec, J.Pietrzak 2007-07-06 Summer Students Practice, JINR, Dubna A.Borowiec, K. Hadyńska, J.Pietrzak

Results for C istopes K. Hadyńska, Ł. Koszuk (not normalized)

Summer Students Practice, JINR, Dubna Conclusions Reaction products formed in fragmentation reaction give contribution to the total yield. Simulation with assumption only one reaction mechanism (projectile fragmentation) cannot describe experimental data. A more sophisticated reaction model needed. 2007-07-06 Summer Students Practice, JINR, Dubna
