TRANSFER CROSS SECTIONS AT NEAR-BARRIER ENERGY FOR THE Mg-24+Zr-90,Zr-92 SYSTEMS
ACTA PHYSICA POLONICA B(2018)
摘要
We have tested the hypothesis that for systems Mg-24 + Zr-90,Zr-92, the shape of the barrier height distribution is not influenced by transfers processes. The experiment was performed using the ICARE detector system at the Warsaw Cyclotron. Having measured the transfer cross sections of the near-barrier collisions of Mg-24 + Zr-90,Zr-92, we have found them to be roughly half of the value obtained for the Mg-20 + Zr-90,Zr-92 systems. From that observation, we conclude that in the Mg-24 + Zr-90,Zr-92 case, the leading cause of washing out the barrier distribution structure is the partial dissipation of relative kinetic energy into the non-collective excitation of the system.
