Abstract

Spectra of two-step γ-ray cascades following the thermal-neutron capture in the ${}^{162}{Dy}$ target were measured. Based on a rigorous modeling procedure, the experimental results are compared with their various theoretical predictions. A satisfactory agreement is reached for the E1 strength function described by the Brink-Axel model and the M1 strength function containing a resonance component at $E_{γ}$ ≊3 MeV. A possible interpretation of this component in terms of the M1 scissors resonance is discussed.
