Dynamics in Production of Superheavy Nuclei in Low-energy Heavy-ion Collisions

  • 摘要: 总结了描述重系统碰撞形成超重核的主要理论模型进展。基于两类反应机制,即熔合蒸发反应和大质量阻尼反应, 对产生超重核的物理过程进行了讨论。分析了超重核形成过程中碰撞系统的俘获、 复合核的形成及蒸发退激描述存在的问题。 基于双核模型分析了合成冷熔合反应和 48Ca诱发全熔合反应之间的超重新核素的可能性。 利用锕系核碰撞的转移反应产生子壳N=162附件丰中子重核的可行性, 研究了壳效应对丰中子核素产生的影响。 进一步讨论了将来基于丰中子强流放射性束合成超重核的可行性。 We present a review of the recent progress of theoretical models on the description of the superheavy nucleus formation in heavy ion collisions. Two sorts of reactions that are the fusionevaporation mechanism and the massive damped collisions to produce superheavy nuclei are discussed. Problems and further improvements of the capture of colliding partners, the formation of compound nucleus and the deexcitation process are pointed out. Possible combinations for the synthesis of the superheavy nuclei in between the roducts of the cold fusion and 48Ca induced reactions are proposed by the calculations based on the dinuclear system model and also compared with other
    approaches. The synthesis of neutronrich heavy isotopes near subshell closure N=162 via transfer reactions in the damped collisions of two actinides and the influence of shell closure on the production of heavy isotopes are investigated. Prospective possibility to reach superheavy nuclei near N=184 via neutronrich radioactive beams of high intensity in the future is discussed.
