摘要

我们研究了 \(^{50,52-54}\)Cr 引发的核聚变反应，用于合成 \(104\le Z\le 122\) 范围内的超重元素。这项研究中使用（^{54}\）Cr射弹产生的截面与之前实验中获得的截面进行了比较。分析得出的估计截面与之前的研究结果一致。在目前的研究中，发现 \(^{53}\)Cr+\(^{243}\)Am 在 236 MeV 时的预测截面为 42 fb，\(^{54}\)Cr+\(^{247}\)Cm 在 236 MeV 时的预测截面为 23.2 fb，\(^{53}\)Cr+\(^{248}\)Bk 在 240 MeV 时的预测截面为 95.6 fb，而\(^{53}\)Cr+\(^{248}\)Bk 在 242 MeV 时的预测截面为 1.因此，这些随激发能量和束流能量变化的预测截面将有助于未来的铈诱导聚变反应研究。

Cr-induced fusion reactions to synthesize superheavy elements

We investigated \(^{50,52-54}\)Cr-induced fusion reactions for the synthesis of the superheavy element in the \(104\le Z\le 122\) range. The cross sections produced in this investigation using \(^{54}\)Cr projectiles were compared with those obtained in prior experiments. The estimated cross sections from this analysis are consistent with the findings of prior studies. From the current study, the predicted cross section was found to be 42fb at 236 MeV for \(^{53}\)Cr+\(^{243}\)Am, 23.2 fb at 236 MeV for \(^{54}\)Cr+\(^{247}\)Cm, 95.6 fb at 240 MeV for \(^{53}\)Cr+\(^{248}\)Bk, and 1.33 fb at 242 MeV for \(^{53}\)Cr+\(^{250}\)Cf. Consequently, these projected cross sections with excitation energy and beam energy will be useful in future Cr-induced fusion reaction investigations.
