Intensity and Multipolarity of Low-Energy Components in the Quasicontinuumγ-Ray Spectrum Followingα- andC12-Induced Reactions

Abstract
Measurements of K-shell ionization yields for (α,xn) and (C12,xn) evaporation residues exclude the existence of a large M1 component in the quasicontinuum spectrum of well-deformed Dy nuclei below 500 keV. Upper intensity limits are deduced for M1, E1, and E2 components.
