Excitation functions based on level density were calculated for proton-induced on yttrium-89 using the TALYS-1.8 code. Hence, production cross-section of the Y(p,x)Zr, Y, Sr, and Rb were computed up to 50 MeV. In this study, the constant temperature model alongside the Fermi Gas model (CGCM) was employed as a default model. For this reason, the a-parameter as an essential parameter in the Fermi Gas formula was modified to obtain the best result. Besides, the Back-shifted Fermi Gas Model (BSFGM) and the Generalized Superfluid Model (GSM) are presented to the deliberation. The outcomes of cross-sections were compared with the experimental data approaching regarding desired consequences.
使用TALYS-1.8代码计算了基于能级密度的质子轰击钇-89的激发函数。因此，计算了能量高达50 MeV时Y(p,x)Zr、Y、Sr和Rb的产生截面。在本研究中，恒温模型与费米气体模型（CGCM）一起被用作默认模型。因此，对费米气体公式中的一个重要参数a进行了修改以获得最佳结果。此外，还提出了后移费米气体模型（BSFGM）和广义超流体模型（GSM）以供讨论。将截面结果与接近预期结果的实验数据进行了比较。
