Here are examples of my recent and current interests in nuclear structure theory.

**a. DIRAC PHENOMENOLOGY and NUCLEAR STRUCTURE.**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.

**b. SELF WEAKENING OF THE TENSOR INTERACTION INSIDE A NUCLEUS.**The fact that the tensor interaction in a valence space appears weaker than in free space can be explained by higher shell admixtures.

**c. SUM RULE TECHNIQUES APPLIED TO NEUTRINO-NUCLEUS INTERACTIONS.**For the electric dipole spin-dipole neutrino capture the summed strength is independent of the deformation of the target.

**d. FERMIONIC SYMMETRIES.**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".

**e. QUADRUPOLE-QUADRUPOLE INTERACTION STUDIES.**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.

**f. NUCLEAR CLUSTERING PHENOMENA.**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.

**g. COLLABORATION WITH LOCAL EXPERIMENTAL GROUPS.**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.
