| 摘 要： | 在修改的Fisher模型框架下,通过定义同质异位素产额比,得出了同质异位素产额比与结合能方程中各能项系数与温度比率之间的简单关联.利用这些关联,可以提取丰中子核结合能方程中的能项系数与温度的比率.

| Abstract: | The correlation between isobaric yield ratios(R) in projectile fragmentation and the energy coefficients in equation of state(EOS) are revisited in the framework of the modified Fisher model.Very simple correlations between the chemical potential(μn-μp)/T,the Coulomb energy term(ac/T),the symmetry energy term(asym/T),the paring energy term(ap/T) and lnR are obtained,Which will help to extract the energy coefficients of the neutron-rich nucleus by analyzing the production cross sections of isobars in projectile fragmentation reactions. |
