Results of our experimental study of the ²⁴Mg${(p,\gamma )}^{25}$Al resonance reaction at E${}_p{}^{lab}=223$ keV are presented. The proton beam energy is varied from 220 to 265 keV. An evaporated Mg target with thick Ta backing is used. We remeasure a mean lifetime of $\tau ={6.04}_{-2.65}^{+3.03}$ fs for the E${}_x=2485.3$ keV level of ²⁵Al, using Doppler shift attenuation (DSA) method. Three most successfully used empirical effective interactions developed for the sd shell by Wildenthal (w), Chung-Wildenthal (cw) and Preedom-Wildenthal (pw), are utilized to calculate energy spectra, spectroscopic factors, beta decay properties, transition probabilities and the lifetime of the resonance state in ²⁵Al within the framework of nuclear shell model. The theoretical results agree reasonably well with the experimental data. However, a detailed study for each set to identify the most preferred interaction for this nucleus is performed. Calculated lifetimes using two of the interactions (w, cw) agree better with the central value of the experimental lifetime of the resonance state measured in the present work.

^我们对24 Mg的实验研究结果${（p,\gamma ）}^{25}$E 处的 Al 共振反应${}_p{}^{我A乙}=223$提出了 keV。质子束能量范围为 220 至 265 keV。使用具有厚 Ta 背衬的蒸发 Mg 靶材。我们重新测量平均寿命$\tau ={6.04}_{-2.65}^{+3.03}$E 的 fs${}_X=2485.3$keV 水平为²⁵ Al，采用多普勒频移衰减 (DSA) 方法。由 Wildenthal (w)、Chung-Wildenthal (cw) 和 Preedom-Wildenthal (pw) 为 sd 壳开发的三种最成功使用的经验有效相互作用被用来计算能谱、光谱因子、β 衰变特性、跃迁概率和核壳模型框架内^{25 Al}共振态的寿命。理论结果与实验数据相当吻合。然而，对每组进行了详细的研究，以确定该核的最优选的相互作用。使用两种相互作用（w，cw）计算的寿命与本工作中测量的共振态实验寿命的中心值更加一致。
