~ 9 Li中的三个triton态

Three triton states in 9Li

K. Muta, T. Furumoto, T. Ichikawa, N. Itagaki

摘要:

我们重点研究轻丰中子核中一种典型的非α团簇结构:9 Li中的三个triton结构。这与12 C中的三个α态(霍伊尔态)的情况类似。阿尔法星系团的行为就像玻色子。然而,tritons具有费米子性质,这三个团簇的结构与12 C有何不同是一个有趣的问题。为此,我们引入了三个triton波函数。此外,还制备了描述9 Li其它低激发态的α +t+n+n波函数,并考虑了它们之间的耦合效应.三个triton组分占主导地位的状态出现在三个triton阈值能量以下,其中三个triton相关是重要的,但是均方根半径并没有增强,相反的α气体状态在12 C和16 O。

英文摘要:

We focus on a characteristic non-alpha cluster structure in light neutron-rich nuclei; three triton structure in 9Li. This is an analogy to the case of three alpha state in 12C (Hoyle state). The alpha clusters behave as bosons. however tritons have Fermionic nature, and how the three cluster structure is different from 12C is an intriguing problem. For this purpose, we introduce three triton wave functions. In addition, alpha+t+n+n wave functions are prepared to describe other low-lying states of 9Li, and the coupling effect between them is taken into account. The states with dominantly the three triton components appear below the three triton threshold energy, where three triton correlation is important, however the root mean square radius is not enhanced contrary to the alpha gas states in 12C and 16O.
