摘要:

在GSI的FRS装置上研究了950 MeV/u的~(238)U射弹裂变产生的~(132)Sn丰中子核的碎裂。这项工作是第一次调查中质量的放射性射弹与一个大的中子过剩的碎裂。剩余核的测量生产截面与可能使用的两阶段反应计划(裂变+碎裂)在未来的稀有离子束设施中生产极富中子的中等质量核有关。此外,新的数据将使人们更好地理解碎裂反应中的“记忆”效应。

英文摘要:

The fragmentation of neutron-rich 132Sn nuclei produced in the fission of 238U projectiles at 950 MeV/u has been investigated at the FRagment Separator (FRS) at GSI. This work represents the first investigation of fragmentation of medium-mass radioactive projectiles with a large neutron excess. The measured production cross sections of the residual nuclei are relevant for the possible use of a two-stage reaction scheme (fission+fragmentation) for the production of extremely neutron-rich medium-mass nuclei in future rare-ion-beam facilities. Moreover, the new data will provide a better understanding of the "memory" effect in fragmentation reactions.
