Multielectron transfer probabilities in 90-keV Ne{sup 9+}-Ne collisions have been measured with respect to the projectile scattering angle {theta} in a range between {theta}=12 and 75 mrad. The projectile final charge state was determined in coincidence with the target-ion final charge state using a time-of-flight technique. For {theta}{gt}45 mrad, projectile and target undergo a complete equilibration of their atomic shells (including the {ital K} shell) leading to the excitation of both collision partners and the autoionization of three electrons on average. A comparison of the measured final charge-state distributions of projectile and target with those obtained in a former experiment with the system 90-keV Ne{sup 7+}-Ne (H. Schmidt-Boecking {ital et} {ital al}., Phys. Rev. A 37, 4640 (1989)) leads to the conclusion that {ital L}- and {ital K}-shell charge transfer can be treated as independent processes. Interference structure in the {ital K}-{ital K} vacancy-transfer probabilities has been observed in the final charge-state probabilities of the heavy-ion''--atom system.
