We have studied polarized electron collisions with Ar in which the target is simultaneously ionized and excited to form Ar⁺(3p⁴(¹D)4p) states. We measured the integrated Stokes parameters of the subsequent fluorescence emitted by the ²F_7/2, ²F_5/2, ²D_5/2, and ²P_3/2 states along the direction of electron polarization. The Rubin-Bederson hypothesis is shown to hold for the L and S multipoles of these states. The electric quadrupole and hexadecapole of the 1D core are derived. By recoupling these moments with …
