摘要
应用微观sdIBM - 2形式体系、正则系综平均法和鞍点近似 ,能计算出核在有限温度下的比热 ,比热峰的存在表明核发生了热激发相变。以Fe核为例作了具体计算 ,并与实验值和量子MonteCarlo结果作了比较。
Using microscopic sdIBM-2 formalism and procedure of canonical ensemble average, finite-temperature specific heat of nuclei is calculated. The existence of peaks in the specific heat shows the occurrence of phase transition of thermal excitation mode. The results are calculated for Fe nuclei and compared with the experimental values and the results calculated by Monte Carlo. These results indicate that this approach is suitable for the description of finite-temperature behavior on nuclei.
