$^6$ He的共振态谱。实验和理论分析

Spectrum of resonance states in $^6$He. Experimental and theoretical analysis

O. M. Povoroznyk, V. S. Vasilevsky

摘要:

我们用实验和理论方法研究了$^{6}$ He的共振态结构。本文介绍了$^{6}$ He三体连续谱的实验研究结果。为了这个目的,我们使用的反应$^{3}$ H $( α,pα)nn$,这是由α粒子与一个triton在束能量$E_α =$ ~67.2兆电子伏的相互作用引起的。在三集团微观模型的框架下,对$^{6}$ He的共振结构进行了理论分析。该模型利用超球谐函数来描述团簇间的动力学。用实验和理论方法发现了新的共振态。确定了共振态的能量、宽度和主要衰减通道,并与不同理论模型和实验结果进行了比较。

英文摘要:

We explore the structure of resonance states in $^{6}$He by experimental and theoretical methods. We present the results of experimental investigations of the three-body continuous spectrum of $^{6}$He. For this aim, we use the reaction $^{3}$H$( α,pα)nn$, which is induced by the interaction of alpha-particles with a triton at the beam energy $E_α =$~67.2 MeV. The theoretical analysis of the resonance structure in $^{6}$He is carried out within the framework of a three-cluster microscopic model. The model exploits the hyperspherical harmonics to describe the intercluster dynamics. The set of new resonance states is discovered by the experimental and theoretical methods. The energy, width, and dominant decay channels of resonances are determined.The obtained results are compared in detail with the results of different theoretical models and experiments as well.
