Abstract

The quaternary, \(\alpha\)-ternary, and binary fission of \(^{249-262}\)No has been studied by considering the role of deformation and angle of orientation. identified by investigating driving potential, yield, and half-lives. The identified fission fragment combination from the cold-valley plot possesses nearly magic and magic numbers of either atomic/neutron numbers or both. The branching ratio of \(\alpha\)-decay with respect to quaternary, \(\alpha\)-ternary, and binary fission is studied. After rigorous investigation between different decay modes, it was is noticed that \(^{249}\)No and \(^{261}\)No undergo spontaneous fission. The quaternary fission of \(^{249-262}\)No is the first of its kind that is not observed in the literature. Spontaneous fission half-lives of \(^{249}\)No and \(^{261}\)No posses shorter half-lives when compared to other possible decay modes such as quaternary fission, \(\alpha\)-ternary, binary fission, alpha, and \(\beta\)-decay. The half-lives of \(^{249}\)No and \(^{261}\)No are found to be 1.05\(\times 10^{-2}\)s and 123, respectively. We hope that the present work will lay the foundation for future investigations.

关于锘的四价、三价和二价裂变的详细研究
通过考虑变形和取向角的作用,研究了(^{249-262}\)No的四价、(α)-三价和二价裂变。从冷谷图中确定的裂变碎片组合在原子数/中子数或原子数/中子数上都具有近乎神奇和神奇的数字。研究了\(α\)-衰变相对于四级、\(α\)-二级和二裂变的分支率。经过对不同衰变模式的严格研究,发现(^{249}\)No 和(^{261}\)No 会发生自发裂变。(^{249-262})No的四级裂变是文献中首次没有观测到的。与其他可能的衰变模式(如四重裂变、二重裂变、α和β衰变)相比,(^{249}\No和(^{261}\No)的自发裂变半衰期较短。发现(^{249})No和(^{261})No的半衰期分别为1.05(times 10^{-2})s和123。我们希望目前的工作能为未来的研究奠定基础。
