摘要:

在双核系统模型的框架内,系统地分析了超重元素Z=117在可能的弹靶组合中的产生。计算结果表明,产物截面强烈依赖于反应体系。本文提出了最佳组合、相应的激发能和蒸发通道,如3 n蒸发通道中的同位素^{48}Ca中的^{248,249}Bk,3 n和4 n通道中的反应^{45}Sc+^{246,248}Cm,以及3 n通道中的系统^{51}V+^{244}Pu。

英文摘要:

Within the framework of the dinuclear system model, the production of superheavy element Z=117 in possible projectile-target combinations is analyzed systematically. The calculated results show that the production cross sections are strongly dependent on the reaction systems. Optimal combinations, corresponding excitation energies and evaporation channels are proposed in this letter, such as the isotopes ^{248,249}Bk in ^{48}Ca induced reactions in 3n evaporation channels and the reactions ^{45}Sc+^{246,248}Cm in 3n and 4n channels, and the system ^{51}V+^{244}Pu in 3n channel.
