e.g. To explain the near vanishing of the A=14 beta decay, one requires a Dirac rather than a Schroedinger approach when higher shell model configurations are admixed.
The fact that the tensor interaction in a valence space appears weaker than in free space can be explained by higher shell admixtures.
For the electric dipole spin-dipole neutrino capture the summed strength is independent of the deformation of the target.
It is noted that certain column vectors representing wave functions of even-even nuclei and their even-odd neighbors are either identical or very similar. This leads to a two to one ratio in the excitation energies and leads us to a "linear hypothesis".
We obtain Elliot's SU(3) energy formula using a simple r-space Q.Q interaction, provided we include the particle-core exchange interactions. We also study the inclusion of the isospin dependent Q.Q interactions, and find that they lead to very strange results unless the spin-orbit interaction is also included.
In Hartree Fock calculations we find, not only clusters, but what we call clusters of clusters, e.g. the near degeneracy in energy of n-particle n-hole states in 40Ca with n=3,4,5,6,7 and 8. The deformation is calculated to be linear in n.
Magnetic Moments of Excited States in the f-p shell. e. g. We discuss the problem of the Z dependence of the g(2+) factors of N=28 isotones, which in simple perturbation theory should lie on a straight line.
