Recent high-resolution spectral scans of several QSOs and Seyfert galaxies show broad Balmer lines and permitted Fe II lines in emission. It is suggested that a careful comparison of the Fe II and Balmer profiles may distinguish between the different proposed mechanisms for broadening of the lines. For a suprathermal-particle model, the hydrogen and Fe II lines arise in the same region, with the Fe II emission produced by the dense ambient gas that is excited by the flux of suprathermal particles. Hence, such a model predicts that the Fe II lines are substantially narrower than the hydrogen lines.
