[en] The level density and the γ-strength function have been extracted experimentally. From the level densities thermodynamical quantities such as temperature and heat capacity can be found. Structures in the micro-canonical temperature are interpreted as the onset of new degrees of freedom by the breaking of Cooper pairs. The S-shape in the heat capacity curves, found within the canonical ensemble, indicates the pairing-phase transition, and a critical temperature for the quenching of pair correlations is found. The pygmy resonance at 3.3(1) MeV in 172Yb has now been established with a strength of B(M1)=6.5(15)μ_N² and M1 multipolarity, the so-called scissors mode. In addition, a strong unexpected enhancement of the radiative strength function (RSF) has been found at low γ-ray energy in medium light Fe nuclei and also in the heavier Mo nuclei
