l-forbidden M1 transitions and pseudospin symmetry - art. no. 014308

Pseudospin symmetry relates the l-forbidden magnetic dipole transition stre ngths between pseudospin partners to the magnetic moments of the involved s tates. These relations are tested against experimental data after correctio n for the fragmentation of the single particle strengths. Within typical un certainties of the experimental spectroscopic factors good agreement is fou nd for a wide, range of shell closures Z = 20-82, N = 20 - 126, and pseudo- orbital angular momenta. Systematic deviations are observed for particle st ates above N = 28 and Z = 50 where the predicted B(M1) values are about an order of magnitude too large.
