摘要

本研究应用相互作用玻色子模型(IBM-I)计算了偶偶富中子\(^{186}\text{W}\)和\(^{186}\text{Os}\)等压线的电约化跃迁概率B(E2) \(\downarrow\)。还计算了这些等压线的比值\(R_{4/2} = E(4_{1}^{+}) / E(2_{1}^{+})\),并报道了这些等压线的SU(3)对称性。\(E(4_{1}^{+})\)和\(E(2_{1}^{+})\)分别表示\(4_{1}^{+}\)和\(2_{1}^{+}\)的能级。我们已经描述了W.u.的B(E2)强度,对于一些低洼四极集体状态的\(^{186}\text{W}\)和\(^{186}\text{Os}\)等压线,与可获得的测量数据进行对比。将\(^{186}\text{W}\)和\(^{186}\text{Os}\)等谱线的电降跃迁概率B(E2) \(\downarrow\)、\(12_1^{+} \rightarrow 10_1^{+}\)、\(10_1^{+} \rightarrow 8_1^{+}\)、\(8_1^{+} \rightarrow 6_1^{+}\)、\(6_1^{+} \rightarrow 4_1^{+}\)、\(4_1^{+} \rightarrow 2_1^{+}\)和\(2_1^{+} \rightarrow 0_1^{+}\)等谱线的电降跃迁概率B(E2)与已有实测数据和其他前人研究结果进行了比较。还计算了B(E2)的系统强度、固有四极矩以及偶偶\(^{186}\text{W}\)和\(^{186}\text{Os}\)等压线的变形参数。这些计算得到的数据与可获得的实测数据吻合良好。在SU(3)极限条件下,系统地推导了在\(^{186}\text{W}\)和\(^{186}\text{Os}\)等压线上的几个砂态转变的IBM-I强度模型。

Electric reduced transition probabilities of \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars through the interacting boson model-I
In this study, we applied the Interacting Boson Model (IBM-I) to compute the electric reduced transition probabilities B(E2)\(\downarrow\) of even-even neutron rich \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars. The ratio \(R_{4/2} = E(4_{1}^{+}) / E(2_{1}^{+})\) has also been calculated for those isobars and the SU(3) symmetry for those isobars has been reported. \(E(4_{1}^{+})\) and \(E(2_{1}^{+})\) indicate the energy level of \(4_{1}^{+}\) and \(2_{1}^{+}\), respectively. We have described the strength of B(E2) in W.u. for \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars of some of the low-lying quadrupole collective states in contrast to obtainable measured data. The electric reduced transition probabilities B(E2)\(\downarrow\) from yrast state gamma transition from \(12_1^{+} \rightarrow 10_1^{+}\), \(10_1^{+} \rightarrow 8_1^{+}\), \(8_1^{+} \rightarrow 6_1^{+}\), \(6_1^{+} \rightarrow 4_1^{+}\), \(4_1^{+} \rightarrow 2_1^{+}\) and \(2_1^{+} \rightarrow 0_1^{+}\) and other bands states and B(E2) ratio of \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars have been compared with obtainable measured data and other previous studies. Also calculated were the systematic strength of B(E2), intrinsic quadrupole moments, and deformation parameters of even-even \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars. The data from these calculations are in good matching with the obtainable measured data. The IBM-I model for the strength of B(E2) has been systematically deduced in SU(3) limit for a few yrasts states transitions in \(^{186}\text{W}\) and \(^{186}\text{Os}\) isobars.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
