Magnetic Dipole Sum Rules for Odd Nuclei
Sum rules for the totaland scissors-mode M1 strength in odd-A nuclei are derived within the single-j interacting boson-fermion model. We discuss the physical content and geometric interpretation of these sum rules and apply them to Er and Dy. We find consistency with the former measurements but not with the latter. 21.60.Fw, 21.10.Re, 23.20.-g, 27.70.+q Typeset using REVTEX 1 The orbital magnet...
متن کاملGround state correlations and structure of odd spherical nuclei
It is well known that the Pauli principle plays a substantial role at low energies because the phonon operators are not ideal boson operators. Calculating the exact commutators between the quasiparticle and phonon operators one can take into account the Pauli principle corrections. Besides the ground state correlations due to the quasiparticle interaction in the ground state influence the singl...
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 ...
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...
