在16 O的四α阈值附近,证明了具有α+ C_(12)(O ~(2+))团簇结构的转动带的存在,其中C_(12)(O ~(2+))中的三个α粒子是局域凝聚的。这是通过以统一的方式研究α+C12(02+)系统的结构和散射来实现的。0+态在15.1 MeV的转动惯量的急剧减小(淬灭)正好高于16 O中的4-α阈值,这表明它可能是α粒子凝聚中超流态的候选者。
The existence of a rotational band with the α+C12(02+) cluster structure, in which three α particles in12C(02+) are locally condensed, is demonstrated near the four-α threshold of16O in agreement with experiment. This is achieved by studying structure and scattering for the α+C12(02+) system in a unified way. A drastic reduction (quenching) of the moment of the inertia of the 0+state at 15.1 MeV just above the four-α threshold in16O suggests that it could be a candidate for the superfluid state in α-particle condensation.
