Consequences of omitting spin-orbit partner configurations on B(E2)'s and quadrupole moments in nuclei

Calculations of B(E2)'s and quadruplole moments in the g_{9/2 region below ^{100} Sn are hampered by the fact that the inclusion of the g_{7/2}configuration leads to model spaces that are too large to handle. We therefore examine lighter nuclei if the fp region where one can easily include all the orbitals, f,{}_{7/2}, p_{3/2}, p_{1/2}and f_{5/2} . We perform such calculations but then take a step back and exclude the f_{5/2} orbital. By comparing the 2 calculations we can hope to get insight into the importance of the missing spin-orbit partner in other regions.

Magnetic g Factors With a Surface Delta Interaction

We examine the consequences of using a surface delta interaction to obtain the nuclear magnetic dipole g factors for 86Kr in a 2 proton hole model space. We find that the g factors of lowest the 2+ and 4+ states are equal to one, or more properly gl. The inclusion of a spin-orbit interaction is also discussed. Comparisons are made with large space calculations.

Isobaric analog states in the f_{7/2} and g_{9/2} shells

Calculations are performed for energies of isobaric analog states with isospins T=2 and T=3 in regions where they have been found experimentally e.g. f-p shell, and regions where they have not yet been found e.g. g_{9/2} near Z=50,N=50. We consider two approaches--one using binding energy formulas and Coulomb energies contained therein and the other using shell model calculations. It is noted that some (but not all) calculations yield very low excitation energies for the J=0^{+} T=2 isobaric analog state in ^{96} Ag.

Isobaric Analog State in ^{96} Ag

Preiviously, in a single j-shell calculation (j=g_{9/2}), we obtained the excitation energy of the T=2 J=0+ isobaric analog state in ^{96} Ag to be a bit below 1 MeV relative to the J=8+ T=1 ground state . We here use binding energy data and Coulomb energy estimates to obtain this same excitation energy and to see if the 2 approaches are consistent.

Streched Magnetic Moments

We note that for a system of 2 nucleons in a stretched case (J=J1+J2) the magnetic moment of the combined system is the sum of the magnetic moments of the 2 constituents. We compile other simple formulas.
