复杂核衰变的微观描述:多峰fission

Microscopic description of complex nuclear decay: multimodal fission

A. Staszczak, A. Baran, J. Dobaczewski, W. Nazarewicz

摘要:

核裂变是一种基本的核衰变,由于其过程的复杂性,我们对它的认识还不完全。本文描述了用非限制核密度泛函理论研究自发裂变。我们的研究结果表明,所观察到的双峰裂变可以解释在多维集体空间的路径对应于不同的几何形状的裂变产物。我们还预言了某些钌、锡和铪同位素的三峰自发裂变的新现象。

英文摘要:

Our understanding of nuclear fission, a fundamental nuclear decay, is still incomplete due to the complexity of the process. In this paper, we describe a study of spontaneous fission using the symmetry-unrestricted nuclear density functional theory. Our results show that the observed bimodal fission can be explained in terms of pathways in multidimensional collective space corresponding to different geometries of fission products. We also predict a new phenomenon of trimodal spontaneous fission for some rutherfordium, seaborgium, and hassium isotopes.
