Kerman-Klein-Dönau-Frauendorf model for odd-odd nuclei: formal theory
The Kerman-Klein-Dönau-Frauendorf (KKDF) model is a linearized version of the non-linear Kerman-Klein (equations of motion) formulation of the nuclear many-body problem. In practice, it is a generalization of the standard core-particle coupling model that, like the latter, provides a description of the spectroscopy of odd nuclei in terms of the corresponding properties of neighboring even nucle...
متن کاملDerivation and assessment of strong coupling core-particle model from the Kerman-Klein-Dönau-Frauendorf theory
We review briefly the fundamental equations of a semi-microscopic coreparticle coupling method that makes no reference to an intrinsic system of coordinates. We then demonstrate how an intrinsic system can be introduced in the strong coupling limit so as to yield a completely equivalent formulation. It is emphasized that the conventional core-particle coupling calculation introduces a further a...
متن کاملApplication of a semimicroscopic core-particle coupling method to the backbending in odd deformed nuclei.
In two previous papers, the Kerman-Klein-Dönau-Frauendorf (KKDF) model was used to study rotational bands of odd deformed nuclei. Here we describe backbending for odd nuclei using the same model. The backbending in the neighboring even nuclei is described by a phenomenological two band model, and this core is then coupled to a large single-particle space, as in our previous work. The results ob...
متن کاملQuasi-Deuteron Configurations in odd-odd N=Z nuclei
The isovector M1 transitions between low-lying T=1 and T=0 states in oddodd N=Z nuclei are analyzed. Simple analytical expressions for M1 transition strengths are derived within a single-j-shell approximation for both j = l+1/2 and j = l − 1/2 cases. The large B(M1) values for the j = l + 1/2 case are attributed to quasi-deuteron configurations. The B(M1) values for the j = l − 1/2 case are fou...
متن کاملShapes of neutron - rich A ≈ 190 odd - odd nuclei
Following from the prediction by Hilton and Mang [1] of “giant backbending” in 180Hf, caused by a collective oblate rotational band crossing the prolate ground-state band, there has been further theoretical investigation of this phenomenon [2–5]. The calculated shape change is understood to be induced by the effects of rotation alignment. It is related to the prediction of a ground-state shape ...
