论文摘要
我们对$ {}^{20} $ ne的$α$颗粒进行了巧合测量，以$ 0^{\ circ} $和衰减充电的颗粒，以搜索alpha-parm condemented凝结状态。我们比较了测得的激发能源光谱和衰减分支比与统计 - 末期模型计算，发现新观察到的状态在$ e_x $ = 23.6 $ = 23.6、21.8和21.2 meV中，in $ {}^{20} $ ne in 4 $ $ consensen $ consensens $ cunsensemed $ cunsens in n $ {}^{20} $ ne。该结果提供了第一个有力的证据，表明这些州是5 $α$冷凝状态的候选人。
We conducted the coincidence measurement of $α$ particles inelastically scattered from ${}^{20}$Ne at $0^{\circ}$ and decay charged particles in order to search for the alpha-particle condensed state. We compared the measured excitation-energy spectrum and decay branching ratio with the statistical-decay-model calculations, and found that the newly observed states at $E_x$ = 23.6, 21.8, and 21.2 MeV in ${}^{20}$Ne are strongly coupled to a candidate for the 4$α$ condensed state in ${}^{16}$O. This result presents the first strong evidence that these states are the candidates for the 5$α$ condensed state.
