论文摘要
从$^{6} $ HE $ 0^+$接地状态到$ 1^ - $ continuum $^{4} $ he+$ n $+$+$ n $的过渡计算了“软偶极” E1强度功能。计算是在超级谐波形式主义中进行的。结果对$^{6} $基态结构和最终状态相互作用的敏感性进行了分析。大型基础计算显示了软偶极强度功能的可靠收敛结果以及$ ^{6} \ mbox {He} \ rightArrow \， ^{4} $ He+$ n $+$ n $+$ n $ n $分离产品的动量相关性。基于动量相关性分析过渡机制。提供了与实验数据的比较。
The "soft dipole" E1 strength function is calculated for the transition from the $^{6}$He $0^+$ ground state to the $1^-$ continuum $^{4}$He+$n$+$n$. The calculations were performed within the hyperspherical harmonics formalism. The sensitivity of the results to the $^{6}$He ground state structure and to final state interactions, are analyzed. The large-basis calculations show the reliably converged results for soft dipole strength function and for momentum correlations of the $^{6}\mbox{He} \rightarrow \, ^{4}$He+$n$+$n$ dissociation products. Transition mechanisms are analyzed based on the momentum correlations. The comparison with experimental data is provided.
