Theoretical investigations will be undertaken concerning the character of the fragmentation phase transition of nuclear matter and to determine the parameters of the nuclear equation of state from the study of the decay products of medium to high energy heavy ion collisions. The work will utilize a new phenomenological model based on bond percolation theory designed for the study of the nuclear fragmentation phase transition, also recently developed techniques which describe heavy ion collisions via a nuclear transport theory which incorporates one- and two-body effects. In cooperation with experimental heavy ion physicists one will attempt to define more meaningful observables for the study of the time history, impact parameter selection, degree of equilibration, and phase space geometry in heavy ion reactions.

通过对中高能重离子碰撞衰变产物的研究，对核物质的破碎相变特征进行理论研究，并确定核状态方程的参数。这项工作将利用一种新的基于键渗透理论的现象学模型，该模型是为研究核碎片相变而设计的，也利用了最近开发的技术，该技术通过包含一体和二体效应的核输运理论来描述重离子碰撞。在与实验重离子物理学家的合作中，我们将尝试为重离子反应的时程、冲击参数选择、平衡程度和相空间几何结构的研究定义更有意义的观测值。
