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

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 of the single particle strengths. Within typical uncertainties of the experimental spectroscopic factors good agreement is found for a wide, range of shell closures Z = 20-82, N = 20 - 126, and pseudo-orbital angular momenta. Systematic deviations are observed for particle states above N = 28 and Z = 50 where the predicted B(M1) values are about an order of magnitude too large.
