ISOSPIN AND CLUSTERING AT MID-RAPIDITY IN INTERMEDIATE ENERGY HEAVY-ION REACTIONS

摘要

The n/p asymmetry of the material found in the mid-velocity or "neck" region of an intermediate energy heavy-ion reaction is determined. In order to accomplish this task data from two different experiments are utilized. While the n/p asymmetry of the light particles is enriched in neutrons Relative to the bulk matter, the total material found at mid-rapidity has an Asymmetry very little different from that of the bulk system. This implies That, for the reaction studied, isospin equilibration plays a minor role in Determining the isospin of the material found in the intermediate velocity Region.
