Implications of pseudospin symmetry on relativistic magnetic properties and Gamow-Teller transitions in nuclei

Recently it has been shown that pseudospin symmetry has its origins in a relativistic symmetry of the Dirac Hamiltonian. Using this symmetry we relate single-nucleon relativistic magnetic moments of states in a pseudospin doublet to the relativistic magnetic dipole transitions between the states in the doublet, and we relate single-nucleon relativistic Gamow-Teller transitions within states in the doublet. We apply these relationships to the Gamow-Teller transitions from Ca-39 to its mirror nucleus K-39. [S0556-2813(99)01105-X].
