为了寻找α粒子的凝聚态，我们对Ne-20在0 °非弹性散射的α粒子和衰变带电粒子进行了符合测量。我们比较了测量的激发能谱和衰变分支比与超导衰变模型的计算，发现新观察到的状态在E-x = 23.6，21.8，和21.2 MeV的Ne-20强耦合的候选人在O-16的4 α凝聚态。这个结果提供了第一个强有力的证据，证明这些状态是5 α凝聚态的候选者。(C)2021年，任作者。由爱思唯尔公司出版
We conducted the coincidence measurement of alpha particles inelastically scattered from Ne-20 at 0 degrees 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 Ne-20 are strongly coupled to a candidate for the 4 alpha condensed state in O-16. This result presents the first strong evidence that these states are the candidates for the 5 alpha condensed state. (C) 2021 The Author(s). Published by Elsevier B.V.
