Cluster decay of the superheavy nuclei \(^{270\text {--}318}118\) has been studied taking Coulomb and proximity potentials as interacting barriers. This study is based on the concept of cold valley. Cluster decay half-lives and other characteristics are computed for various clusters. The predicted \(\alpha \) decay half-life values are compared with other theoretical models and also with the sole experimental value. Plots connecting half-lives with the neutron number of the daughter nuclei as well as with the neutron number of the parent nuclei, strongly indicated neutron shell closure at \(N=184\). Also, we noted that proton shell closure occurs at \(Z=114\). From our studies, we noted that the nuclide \({}_{184}^{298} {114}\), which is doubly closed, is very stable and we could reach the inference that \({}_{184}^{298} {114}\) is the most probable nuclide to be the centre of island of stability.

已经研究了超重核\(^{270\text {--}318}118\) 的簇衰变，以库仑势和邻近势为相互作用势垒。本研究基于冷谷的概念。为各种簇计算簇衰减半衰期和其他特征。将预测的\(\alpha \)衰减半衰期值与其他理论模型以及唯一的实验值进行比较。将半衰期与子核的中子数以及母核的中子数连接起来的图，强烈表明\(N=184\)处的中子壳闭合。此外，我们注意到质子壳闭合发生在\(Z=114\)。从我们的研究中，我们注意到核素\({}_{184}^{298} {114}\)是双闭的，非常稳定，我们可以得出\({}_{184}^{298} {114}\)是最有可能成为稳定岛中心的核素。
