Nature of the Pygmy Resonance in Continuous Gamma-Spectra

Description

Two-step-cascade spectra of the 171Yb(n, γγ)172Yb reaction have been measured using thermal neutrons. They are compared to calculations based on experimental values of the level density and radiative strength function obtained from the 173Yb(3He,αγ)172Yb reaction. The multipolarity of a 6.5(15) μN2 resonance at 3.3(1) MeV in the strength function is determined to be M1 by this comparison
