Abstract
The three-body nuclear and molecular resonances for \(^{135}_{~55}\)Cs+\(^2_1\)H+\(^2_1\)H, and \(^{133}_{~55}\)Cs+\(^3_1\)H+\(^3_1\)H systems are calculated in “cuboctahedron \(^{135}_{~55}\)Cs\(^2_1\)H\(_2\)\(^\textrm{A}_{46}\)Pd\(_{12}\) and \(^{133}_{~55}\)Cs\(^3_1\)H\(_2\)\(^\textrm{A}_{46}\)Pd\(_{12}\) clusters” in a very wide range from 0.01[fm] to several hundreds of nm in “one stretch” with more than “100 significant figures”, where the mass number A of Pd could be 102, 104, 105, 106, 108, 110 but neglected hereafter, because Pd isn’t concerned directly with the nuclear reaction. We obtained several new “three-ion resonance states” between the expected molecular CsH\(_2\) ground state and the first excited state in cuboctahedron CsH\(_2\)Pd\(_{12}\) cluster, where H represents either a \(^1_1\)H, a \(^2_1\)H, or a \(^3_1\)H, respectively. The molecular “ground and the first excited states” in the cluster are derived by the Kohn-Sham equation or the ADF package which could mainly describe many electrons rather than cores of ions. We found that the E2 transition times from some CsH\(_2\)\((7/2^+)\) resonance states (or the IOS states) to the nuclear \(^{139}_{~57}\)La \((7/2^+)\) ground state are about \(\tau =10^{-1}\sim 10^{-6}\)sec for five traditional potentials, and \(\tau =10^{-2}\sim 10^{-8}\)sec for six potentials with our long range three-body force (3BLF) where the “molecular resonances” can strongly interfere with the “nuclear resonances”. The thermal nuclear “critical reaction value” (or fusion constant) and/or ultra low energy corresponding value: \(C_\mathrm{high/low}\)=(duration time)\(\times \)(density)\(\times \)(energy or temperature) are compared. It was found that \(C_\textrm{low}\) is almost the same order as \(C_\textrm{high}\) or more. Finally, an ignition method for the synthesis will be discussed.
期刊介绍:
The journal Few-Body Systems presents original research work – experimental, theoretical and computational – investigating the behavior of any classical or quantum system consisting of a small number of well-defined constituent structures. The focus is on the research methods, properties, and results characteristic of few-body systems. Examples of few-body systems range from few-quark states, light nuclear and hadronic systems; few-electron atomic systems and small molecules; and specific systems in condensed matter and surface physics (such as quantum dots and highly correlated trapped systems), up to and including large-scale celestial structures.
Systems for which an equivalent one-body description is available or can be designed, and large systems for which specific many-body methods are needed are outside the scope of the journal.
The journal is devoted to the publication of all aspects of few-body systems research and applications. While concentrating on few-body systems well-suited to rigorous solutions, the journal also encourages interdisciplinary contributions that foster common approaches and insights, introduce and benchmark the use of novel tools (e.g. machine learning) and develop relevant applications (e.g. few-body aspects in quantum technologies).
