E. Delgiudice et G. Preparata, ELECTRODYNAMIC LIKE-CHARGE ATTRACTIONS IN METASTABLE COLLOIDAL CRYSTALLITES, Modern physics letters B, 12(21), 1998, pp. 881-885
We show that the recent observation of like-charge attractions in meta
stable colloidal systems is naturally and quantitatively explained by
the collective interactions among the surface electrons of the colloid
al microspheres, predicted by QED.
