论文摘要
方法:测量$^{6} $ HE+$ $α$散射的激发功能,激发能量中的填充状态范围从4.5 meV到$^{10} $中的8 meV,使用$^6 $ he He He Rare-Esotope Beam和厚氦气目标。 结果:未观察到$^{10} $中没有新的激发状态。已经获得了假设元的6 $^+$状态的可能程度的严格限制。 结论:$α$:2n:$α$分子状的旋转频段配置的高旋转成员,被认为在6.18 meV处的0 $^+$ bandhead在6.18 MeV中,或者与$^{6} $ HE(G.S)(g.s g.s)+$ $ a $ cannels不存在,或者与$^{6} $ a $ cannels不存在。
Method: Measuring excitation functions for $^{6}$He+$α$ scattering, populating states in the excitation energy range from 4.5 MeV to 8 MeV in $^{10}$Be using a $^6$He rare-isotope beam and a thick helium gas target. Results: No new excited states in $^{10}$Be have been observed. Stringent limitation on the possible degree of $α$-clustering of the hypothetical yrast 6$^+$ state has been obtained. Conclusions: The high-spin members of the $α$:2n:$α$ molecular-like rotational band configuration, that is considered to have a 0$^+$ bandhead at 6.18 MeV, either do not exist or have small overlap with the $^{6}$He(g.s.)+$α$ channel.
