We use recently measured cold photoassociation and two-photon data to extract the singlet and triplet accumulated radial phases of interacting ground-state lithium atoms. Using the resulting values we predict scattering lengths, Feshbach resonances, and exchange decay rates for cold collisions between {sup 7}Li and {sup 6}Li atoms that are of interest for the possibility of sympathetic cooling of {sup 6}Li and for the coexistence of the bosonic and fermionic quantum-degenerate phases of {sup 7}Li and {sup 6}Li. In addition, we calculate scattering lengths and exchange decay rates for cold collisions between identical lithium isotopes in different hyperfine states. These quantities are used to examine the possibilities of coexisting {sup 7}Li Bose condensates and of evaporatively cooling coexisting {sup 6}Li subsystems. {copyright} {ital 1997} {ital The American Physical Society}
