We study theoretically K shell-K shell single electron capture in ion-
ion collisions at relativistic impact energies in reactions involving
highly charged ions. We obtain differential and total cross sections f
or the charge transfer reaction U92+ + U91+ with and without spin-flip
of the captured electron by using two different distorted wave models
: the Matrix Continuum Intermediate State and the Matrix Continuum Dis
torted Wave. We analyse the influence of the double dispersion mechani
sms on the cross sections. We also study the contributions to cross se
ctions coming from collisions at different impact parameters. At small
impact parameters the reduced transition probabilities are dominated
by spin-flip reactions.
