摘要：

We have measured the absolute polarization of the 2p(6) S-1(0)- 2p(5)((20)(3/2))3s[3/2](0)(2) magnetic quadrupole transition in Ne-like barium, excited in an electron-beam ion trap at a variety of energies. We find strong evidence for the existence of resonant excitation processes that are not explained by our collisional-radiative calculations even when the polarization arising from impact excitation is included. At energies well away from where the resonances occur, the agreement between experiment and theory is good.
