摘要

在巨正则模型下，利用两相似反应系统的同质异位素产额比之差(Isobaric yield ratio difference

IBD)，研究中等质量余核化学势与反应系统的关联。结果表明，两相似反应系统的Dm/T之差Dm21/T对两反应系统双中质比(N/Z)21很敏感，说明Dm/T对反应系统具有依赖性。同时发现，当(N/Z)21=1.17时，两反应系统不同余核的Dm21/T趋于一个常数，说明在这两个系统中，利用IBD和同位旋标度方法获得的对称能信息更合理，且符合得更好。

Abstract

Background: Chemical properties of projectile residues are important in studying the symmetry energy using isobaric yield ratio (IYR) and isoscaling methods. Purpose: The correlation between chemical properties of intermediate mass residues and reaction systems is to be studied. It is hoped that the symmetry energy information can be extracted more precisely. Methods: In the framework of the grand-canonical ensemble theory

the Dm/T difference between two heave-ion reactions

which was labeled as Dm21/T

was extracted by using isobaric yield ratio difference (IBD) method. Results: By comparing the Dm21/T among six different combinations 48Ca+9Be/40Ca+9Be

48Ca+9Be/58Ni+9Be

64Ni+9Be/40Ca+9Be

64Ni+9Be/58Ni+9Be

58Ni+9Be/ 40Ca+9Be

48Ca+9Be/ 64Ni+9Be

it was proved that Dm/T depends on the reaction system. In different reactions

the values of Dm/T were not fixed. When the double neutron-to-proton ratios (N/Z)21=1.17

Dm21/T can be approximately a constant. Conclusion: Symmetry energy can be more reasonable in isoscaling and IBD methods

when double neutron-to-proton ratios (N/Z)21=1.17 between two similar reaction system.Cited
