Pseudospin Symmetry in Real Nuclei

  • The pseudospin symmetry and its approximation in real nuclei are discussed. When the sum of the vector and scalar potentials is a constant, there will be an exact pseudospin degeneracy and even the usual intruder orbits will have degenerate partners. For real nuclei, the pseudospin symmetry is approximate, and the partners of the usual intruder orbits will disappear. The reason behind this is the contribution of the pseudo spin orbit potential.

Abstract: The pseudospin symmetry and its approximation in real nuclei are discussed. When the sum of the vector and scalar potentials is a constant, there will be an exact pseudospin degeneracy and even the usual intruder orbits will have degenerate partners. For real nuclei, the pseudospin symmetry is approximate, and the partners of the usual intruder orbits will disappear. The reason behind this is the contribution of the pseudo spin orbit potential.
