In the present work, we investigate the entrance channel effects on the alpha decay probabilities for the neutron and proton induced reactions for target mass A=55 from few MeV up to 20 MeV. In particular, we studied two combinations, ⁵⁵Fe(n,α)⁵²Cr and ⁵⁵Mn(p,α)⁵²Cr; ⁵⁵Mn(n,α)⁵²V and ⁵⁵Cr(p,α)⁵²V reactions. Each combination is producing the same compound nucleus at the same excitation energy, but with different $J^{\pi }$ distributions. We investigate how the difference in the $J^{\pi }$ distributions of the compound nuclei at the same excitation energy formed by the neutron and proton induced reactions influence the alpha decay channel. The theoretical simulation is done using the nuclear reaction code TALYS-1.9. The results are compared with experimental results whenever available, and are discussed in detail.

在当前的工作中，我们研究了入射通道对目标质量A = 55的中子和质子诱发的反应的α衰变概率的影响，从几兆电子伏特到20兆电子伏特。特别是，我们研究了⁵⁵ Fe（n，α）⁵² Cr和⁵⁵ Mn（p，α）⁵² Cr的两种组合。⁵⁵ Mn（n，α）⁵² V和⁵⁵ Cr（p，α）⁵² V反应。每种组合都以相同的激发能产生相同的化合物核，但具有不同的激发能${Ĵ}^{\pi }$分布。我们调查了${Ĵ}^{\pi }$在由中子和质子诱发的反应形成的相同激发能下，化合物核的分布会影响α衰变通道。使用核反应代码TALYS-1.9完成理论模拟。将结果与可用的实验结果进行比较，并进行详细讨论。
