Özet

Two-step-cascade spectra of the Yb-171(n, gammagamma)Yb-172 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 Yb-173(He-3, alphagamma)Yb-172 reaction. The multipolarity of a 6.5(15) mu(N)(2) resonance at 3.3(1) MeV in the strength function is determined to be M1 by this comparison. (C) 2004 MAIK "Nauka/Interperiodica".
