Excitation functions for the ^natTi(³He, x)^44g,mSc nuclear reactions were measured from respective threshold up to 55 MeV by using a conventional stacked-foil activation technique combined with HPGe γ-ray spectroscopy. Individual cross-section values for the production of ^44mSc and ^44gSc were separated using a proper mathematical method on the basis of their individual gamma lines and the data for ^44gSc are reported here for the first time. The default parameters of TALYS-1.8 are unable to provide the ^44mSc/^44gSc isomeric cross-section ratio values consistent with those obtained experimentally. However, an adjustment of the level density model and optical model potentials together with some other relevant parameters, especially the spin cut-off parameter with the variation of η (=I_eff/I_rigid) were found to be effective to reproduce the measured cross-sections. A similar parameter adjustment could be useful for accurate prediction of other medium mass isomeric pairs (i.e., when the metastable state is longer-lived than the ground state) where either experimental data are not available, or an expensive experiment is required to obtain them.

通过使用常规的叠层箔活化技术结合HPGeγ光谱法，从相应的阈值到55 MeV，测量了^Nat Ti（³ He，x）^44g，m Sc核反应的激发函数。根据各自的伽马线，使用适当的数学方法将生产^44m Sc和^44g Sc的各个横截^面值分开，并首次在此报告^44g Sc的数据。TALYS-1.8的默认参数无法提供^44m Sc / ^44g    Sc同分异构体的横截面比率值与实验获得的一致。然而，发现调整水平密度模型和光学模型的电势以及其他一些相关参数，尤其是随着 η （= I _eff / I_刚性）变化的自旋截止参数可以有效地重现所测量的交叉。部分。在无法获得实验数据或需要昂贵实验来获得它们的情况下，类似的参数调整可用于准确预测其他中等质量异构对（即，亚稳态比基态寿命长）。
