We show that a natural explanation for characteristic features (angular momentum and radial quantum numbers) of pseudospin doublets and intruder levels in nuclei can be obtained by combining the relativistic attributes of pseudospin symmetry with kno

We review recent developments that show that pseudospin symmetry is an approximate relativistic symmetry of the Dirac Hamiltonian with realistic nuclear mean field potentials.

The identification of pseudospin symmetry as a relativistic symmetry of the Dirac Hamiltonian is used to explain the structure of radial nodes occurring in pseudospin doublets and to illuminate the special status of nodeless intruder states in nuclei

Pseudospin symmetry relates the l-forbidden magnetic dipole transition strengths between pseudospin partners to the magnetic moments of the involved states. These relations are tested against experimental data after correction for the fragmentation o

We use the empirical evidence that F-spin multiplets exist in nuclei for only selected states as an indication that F-spin can be regarded as a partial symmetry. We show that there is a class of non-F-scalar IBM-2 Hamiltonians with partial F-spin sym

We show that the generators of pseudospin symmetry are the non - relativistic limit of the generators of an SU(2) symmetry which leaves invariant the Dirac Hamiltonian with scalar and vector potentials equal in magnitude but opposite in sign, $V_V =

Shell model level densities are calculated for many light nuclei assuming the valence nucleons move in the ( ls , 0 d , 0 f case7 2 ) orbits about an inert 16O core and interact via realistic effective two-nucleon interactions. These level densities

In order to calculate scalar averages of the product of any operators, over a finite number of many particle states, a diagramatic method is developed. This is generalized to the configuration averages and it is found that configuration averages triv
