用同位旋相关的晶格气体模型系统地研究了Z =5 4的同位素和A =12 9的同质异位素热发射体的粒子发射的特性 ,阐述了发射体系的同位旋对中子、质子和带电粒子产额 ,以及轻粒子的同位素比及同位素对的比的影响 .同时 ,还比较了在同位旋相关作用势下和同位旋不相关作用势下碎片产物特性的差异 .发现了不同质量区间 (轻粒子、中等质量碎片和重余核 )的产物的平均中子 质子比 ,在同位旋相关的或不相关的作用下它们有十分不同的温度依赖性 .发现核气态 (轻粒子 )的 要大于核液态 (重余核 )的 ,也就是说在液气共存时的气态有更大的同位旋非对称性 .对于同位旋不相关作用势的情况 ,轻粒子的同位素产额比几乎与发射源本身的同位旋无关
The characteristics of particle emission of isotopes of Z = 54 and isopotential heat emitters of A = 129 were investigated systematically using the isospin-related lattice gas model. The isospin neutron, Proton and charged particle yield, as well as the ratio of isotope ratio and isotope ratio of light particles, and also compared the difference of the product characteristics of fragments under the irrelevant role of isospin-related potential and isobaric relationship. The average neutron proton ratio of the products in the mass interval (light particles, medium-quality fragments and heavy nuclei) have very different temperature dependencies under or without related isospin. The of the gaseous (lighter) particles is larger than the of the nuclear liquid (heavy nuclei), meaning that the gaseous state has greater isospin asymmetry at the time of liquid gas coexistence. Irresistible potential, the light-particle isotope yield is almost independent of the isomerization of the source itself
