Electric and Magnetic Moments of Odd-Neutron Nuclei on the Single Configuration Model

Abstract Without taking account of the effect of conf iguration mixing, we attempt to derive the electric moments as well as magnetic moments of odd-neutron nuclei on the basis of the single configuration model. The quadrupole moments of odd-neutron nuclei may be obtained by the promotion of two protons from the zeroth order proton state of seniority zero to the states of seniority two. These mixing coefficients of the ground state are determined by fitting the wave function to the magnetic moment of the odd-neutron nucleus considered. Thus we find a fairly good agreement between the calculated and observed values except for the nuclei with very large quadrupole moments and for the nuclei in the vicinity of each closed shell. The quadrupole and hexadecapole moments of the first excited state of 111Cd are also evaluated.

Reevaluation of the Electric Quadrupole Moment of the Deuteron

Recent high-precision experiments by the HD beam magnetic resonance method gave a formula for calculating nuclear quadrupole coupling constants more accurately than former experiments and also more precisely than the experimental value of the pure deuterium molecule. At present, the most accurate value of the quadrupole moment of the deuteron (error 4%) evaluated through the electromagnetic interaction is considered as based upon the theoretical calculation of q obtained by the use of Newells variational function. A refinement of Newells method was made which appears to yield an error of only 0.6%. (A.C.)
