We find that the interparticle interactions could induce the instability of the atom-trimer dark state in some ...<br/>[Phys. Rev.

X. Chen, K. Kirby, N. S. Brickhouse, T. Lin, and E. Silver<br/>We have developed a method within the Dirac R -matrix theory to calculate x-ray line polarization resulting from electron-impact excitation to excited-state magnetic sublevels of complex ions. We apply this method to the excitation of two well-known x-ray lines of Fe XVII, 3C (λ=15.015 Å) and ...<br/>[Phys. Rev. A 79, 062715] Published Tue Jun 30, 2009 G. X. Chen, K. Kirby, N. S.
