我们研究了从多碎片数据中提取对称能量的可能性。小野等人早期提出的大正则公式的适用性。 [物理。 Rev. C 68, 051601(R) (2003)]在微规范框架内测试了有限激发核的情况。除了大的残余核外，特别是当大的源被高度激发时，获得了相对较好的结果。最后讨论了二次粒子发射的影响以及从实验观测值推断相关信息的程度。
We investigate the possibility of extracting the symmetry energy from multifragmentation data. The applicability of the grandcanonical formula earlier proposed by Ono et al. [Phys. Rev. C 68, 051601(R) (2003)] in the case of finite excited nuclei is tested within a microcanonical framework. Relatively good results are obtained except for large residual nuclei, especially when large sources are highly excited. Effects of secondary particle emission and the extent in which relevant information may be inferred from experimental observables are finally discussed.
