Abstract: (APS)
The resolution of reaction filters for intermediate-energy heavy-ion collisions based upon charged-particle and neutron multiplicity measurements with 4π coverage is compared for 112Sn+112Sn and 124Sn+124Sn collisions at E/A=40 MeV. The quality of event characterization is inferred from the azimuthal correlations of α particles emitted at intermediate rapidity and from the 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.
