Theory of Collective Excitations in Spherical Odd-Mass Nuclei. III: Electromagnetic Properties of the Anomalous Coupling States

Abstract

Various electromagnetic properties of the anomalous coupling states with spin (j-1) are shown to be well explained by the new viewpoint of the dressed n-quasi-particle modes proposed in a previous paper. In this point of view, the anomalous coupling collective states with spin (j-1) are considered as the dressed three-quasi-particle modes, which are regarded as a kind of elementary excitation modes in odd-mass nuclei. The effects of couplings between dressed three-quasi-particle modes and one-quasi-particle modes are also discussed in this connection, including those with spin j, (j-1) and (j-2).
