The pygmy resonance at 3.3(1) MeV in Yb-172 has now been established with a strength of B(M1) = 6.5(15)mu(2)(N) and M1 multipolarity. In addition, a strong unexpected enhancement of the radiative strength function has been found at low gamma-ray energy in medium light Fe nuclei and also in the heavier Mo nuclei.
