Interactions related to A-B phases exist between fluxons with Phi = al
pha Phi(0), alpha not equal integer when the fluxons are actually imme
rsed in a region with non-vanishing mobile charge density. In particul
ar, for the interesting case of alpha = 1/2 we find that this force is
attractive. We briefly comment on the prospects of observing such for
ces. (C) 1997 Published by Elsevier Science B.V.
