A quark model which includes both scalar and vector contributions to the reaction {bar p}p {yields} {bar {Lambda}}{Lambda} is presented. DWBA calculations of differential cross sections, polarizations and spin correlation coefficients are compared to experimental results at several energies. The results are sensitive to details of the reaction mechanism and to the parameters of the {bar {Lambda}}{Lambda} interaction. 10 refs., 5 figs.
