Alfvén-cyclotron fluctuations of successively shorter wavelengths in collisionless plasmas transfer energy via cyclotron resonances to ions of successively larger charge-to-mass ratios. Theories and simulations predict that this interaction leads to T⊥/T&|slash; > 1 for each resonant ion species, where the subscripts refer to directions relative to the background magnetic field. Here observations of the slow solar wind near 1 AU by the plasma and magnetic field instruments on the ACE spacecraft are reported which show the predicted signatures of such wave-ion interactions in the alpha particle anisotropies, as well as correlations between the enhanced temperatures of these ions and the amplitudes of magnetic field fluctuations.
