The resolution of reaction filters for intermediate-energy heavy-ion collisions based upon charged-particle and neutron multiplicity measurements with 4{pi} coverage is compared for {sup 112}Sn+{sup 112}Sn and {sup 124}Sn+{sup 124}Sn collisions at E/A=40 MeV. The quality of event characterization is inferred from the azimuthal correlations of {alpha} particles emitted at intermediate rapidity and from the {ital Z} distributions of projectilelike fragments emitted at forward angles. For central and midimpact parameter collisions, the associated charged-particle multiplicity appears to provide better impact-parameter selection than the associated neutron multiplicity. {copyright} {ital 1997} {ital The American Physical Society}
