通过研究两个系统$^{58}Ni$+$^{58} Ni$和$^{58} Ni $+$^{197}Au$，在入射能量52- 74 μ M范围内，探讨了半周边碰撞中同位旋扩散随耗散能的变化.在相空间的前向部分的轻产品的多重性的仔细检查清楚地显示了这些产品的中子丰度的影响的目标的同位旋。一个渐进的同位旋扩散时，观察到碰撞变得更加中心，与相互作用的时间。
Isospin diffusion in semi-peripheral collisions is probed as a function of the dissipated energy by studying two systems $^{58}Ni$+$^{58}Ni$ and $^{58}Ni$+$^{197}Au$, over the incident energy range 52-74\AM. A close examination of the multiplicities of light products in the forward part of phase space clearly shows an influence of the isospin of the target on the neutron richness of these products. A progressive isospin diffusion is observed when collisions become more central, in connection with the interaction time.
