“…In a generic situation the amplitude t varies together with some control operator x, and for sufficiently weak detector-system coupling, the dependence t(x) can be approximated as linear. Dynamics of such linear measurements is well understood (see, e.g., [20,21]).…”

“…In recent years, there has been a great deal of interest in muon-catalyzed fusion (µCF) in a mixture of the three gases deuterium, tritium, and hydrogen (D-T-H) for muoncycling enhancement. But published papers frequently contradict each other, those against show that addition of protium to a D-T mixture leads to a significant decrease in the cycling rate [16][17][18][19][20]. In a mixture of the three gases, D-T-H, the muonic molecules dtµ despite reactions (4) and (5) are also produced in the resonance reaction…”

Recent experimental and theoretical studies on muon-catalyzed fusion in a mixture of three gases, D-T-H, have shown that the muon-cycling-rate changes obtained are mostly in contradiction with each other and depend strongly on the physical conditions of the system. In this paper, we have considered the muon-cycling rate and its relevant nonlinear dynamical equations for mixtures of D-T and D-T-H in practical conditions where the muon-cycling rate is temperature; density of the mixture; and relative-particle concentration (deuterium, tritium, and hydrogen) dependent. Our theoretical method has shown that addition of protium to a D-T mixture leads to a significant decrease in the cycling rate, namely, by a factor of more than 15 in the liquid mixture and more than three in the gaseous mixture at 300-600 K. We show that the results obtained for given experimental conditions are in very good agreement with recent experimental values of Joint Institute for Nuclear Research in Dubna. The given reliable theoretical method leads us to determine the optimal condition of the muon-cycling rate such as relative-particle concentration in the resonance-temperature range at liquid hydrogen density, = 1. It is shown that for a deuterium and tritium relative concentration of C d = C t = 0.45 with C p = 0.1 and ω s = 0.0029, a muon-cycling rate of 199 in the dtµ branch at 800 K is achievable, which compared to the D-T system in optimal conditions, still has a 29% enhancement. Finally, by energy-gain evaluation of resonance-muon-catalyzed fusion, we show that even this key step in high-yield µCF is far, far away from sufficiently minimal values to be of interest for practical applications of such a system. PACS No.: 25.30MRésumé : De récents résultats théoriques et expérimentaux sur la fusion avec catalyse muonique dans des mélanges des trois gaz, D-T-H, ont montré que les changements dans les taux du cycle (de recyclage) des muons sont en contradiction, avec une forte dépendance sur les conditions physiques du système. Ici, nous étudions le taux de recyclage du muon avec ses équations dynamiques non linéaires pertinentes pour des mélanges D-T et D-T-H, sous des conditions réalistes où le taux est fonction de la température, de la densité et des concentrations relatives (de H, D et T). Notre méthode théorique montre que l'addition du protium au mélange D-T cause une décroissance significative du taux de recyclage, plus précisément, par un facteur de 15 et plus dans le mélange liquide et de plus de 3 dans le mélange gazeux à 300-600 K. Nous montrons que les résultats obtenus pour les paramètres expérimentaux choisis sont en bon accord avec les résultats d'expériences récentes au JINR. Les résultats théoriques les plus fiables nous suggèrent les conditions optimales, sur les densités relatives par exemple, pour le recyclage des muons dans le domaine de la température de résonance et pour une densité égale à celle de l'hydrogène liquide, = 1. Nous montrons qu'avec les concentrations relatives C d = C t = 0,45 et C p = 0,1 et avec ω s ...

“…It is similar to our previous reported measurement [4] using D 2 molecules. Other experimental efforts in liquid/gaseous triple mixtures attempt to measure this rate, however interpretation is difficult because of the complex kinetics involved [5,6]. In the present experiment, solid layers were made by freezing hydrogen isotopic gases and mixtures onto two 51 µm thick gold target foils maintained at 3K.…”

Measurement of the ResonantdμtMolecular Formation Rate in Solid HD

Measurements of muon-catalyzed dt fusion ( d(mu)t-->4He + n + mu(-)) in solid HD have been performed. The theory describing the energy dependent resonant molecular formation rate for the reaction (mu)t + HD-->[(d(mu)t)pee](*) is compared to experimental results in a pure solid HD target. Constraints on the rates are inferred through the use of a Monte Carlo model developed specifically for the experiment. From the time-of-flight analysis of fusion events in 16 and 37 microg x cm(-2) targets, an average formation rate consistent with 0.897+/-(0.046)(stat)+/-(0.166)(syst) times the theoretical prediction was obtained.
