Anupriya Jain, Suneel Kumar, Rajeev K. Puri

摘要:

利用与同位旋相关的量子分子动力学模型,研究了电荷不对称性和与同位旋相关的截面对椭圆流不同方面的影响。对$^{124}X_{m}+^{124}X_{m}$(其中m =(47、50、53、57和59))和$^{40}X_{n}+^{40}X_{n}$(其中n=(14、16、18、21和23))的反应进行了模拟。研究表明,椭圆流对截面的同位旋有很强的依赖性。随着N/Z的增加,跃迁能几乎保持不变。与实验测量得到了很好的协议。

英文摘要:

Using the isospin dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin dependent cross-section on different aspects of elliptical flow. Simulations have been carried out for the reactions of $^{124}X_{m}+^{124}X_{m}$, where m = (47, 50, 53, 57 and 59) and $^{40}X_{n}+^{40}X_{n}$, where n= (14, 16, 18, 21 and 23). Our study shows that elliptical flow depend strongly on the isospin of cross-section. The transition energy remains almost constant with increase in N/Z of the system. A good agreement is obtained with experimental measurements.
