本文从原始γ射线中提取了~（161，162）Dy和~（171，172）Yb核的低自旋能级密度。在正则系综的框架下推导了核的热容。的热容量表现出S形形状作为温度的函数，这被解释为指纹的相变从一个强相关到一个不相关的阶段。发现对关联猝灭的临界温度为Tc=0.50（4）MeV。
The level density at low spin in the 161,162-Dy and 171,172-Yb nuclei has been extracted from primary gamma rays. The nuclear heat capacity is deduced within the framework of the canonical ensemble. The heat capacity exhibits an S-formed shape as a function of temperature, which is interpreted as a fingerprint of the phase transition from a strongly correlated to an uncorrelated phase. The critical temperature for the quenching of pair correlations is found at Tc=0.50(4) MeV.
