06.02.2017 - FLNR Scientific Seminar, "Peculiarities of total cross sections of reactions with weakly bound 6He, 9Li nuclei", 15-30 Flerov Lab Conference Hall.
Speakers: Sobolev Yu.G., Naumenko M.A.
The results of measurements of energy dependence of σR(E) total cross sections for 4,6He + Si and 6,7,9Li + Si reactions in 5−40 А•MeV energy range are presented here. A brief survey of experimental techniques is given. A considerable local enhancement of σR(E) total cross section was discovered in 4,6He + Si and 6,7,9Li + Si reactions in 10−30 А•MeV energy range. Nonstationary microscopic model was used for the theoretical analysis of the experimental data.
Within the developed model the discovered peculiarities of σR(E) of 4,6He + Si and 6,7,9Li + Si reactions are explained by the influence of weakly bound outer neutrons of projectiles.
