We study the effects of a bubble configuration in a nucleus on heavy-ion collisions at a few tens and hundreds A MeV. We first investigate the bubble structure of Hg using the relativistic continuum Hartree–Bogoliubov theory and then study the Hg + Pb and Hg+ Hg reactions using the DaeJeon–Boltzmann–Uehling–Uhlenbeck (DJBUU) transport model. To see the role of the bubble structure, we consider the maximum density of the produced nuclear matter, directed flow of neutrons and protons, and ratio. We observe that the maximum density is smaller with a bubble nucleus, and the directed flow of nucleons and ratio may depend on the bubble structure.

重离子碰撞中的核气泡构型
我们研究了原子核中的气泡配置对几十和几百 A MeV 的重离子碰撞的影响。我们首先研究气泡结构 Hg 使用相对论连续统 Hartree-Bogoliubov 理论,然后研究 汞 + 铅和 汞+ 使用 DaeJeon-Boltzmann-Uehling-Uhlenbeck (DJBUU) 传输模型的汞反应。为了了解气泡结构的作用,我们考虑产生的核物质的最大密度、中子和质子的定向流动,以及 比率。我们观察到气泡核的最大密度较小,核子的定向流动和 比率可能取决于气泡结构。
