Phys. Rev. C 63, 021306(R) (2001) [5 pages]Critical temperature for quenching of pair correlations
The level density at low spin in the 161,162Dy and 171,172Yb nuclei has been extracted from primary γ 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±0.04(stat)±0.08(syst) MeV. © 2001 The American Physical Society URL:
