Low Energy Nuclear Reactions
Paták, Roman ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor thesis deals with collection and arrangement of information about cold fusion. The introduction describes discovery of the cold fusion, problems associated with it and the response of the scientific community. Furthermore, there are explained the assumed basic conditions of its emergence and some of the experiments are detailly described. Finally, the possible direction of the cold fusion utilization in the future is easily outlined.

Production Of Isomeric States In The Deuteron-Induced Reaction Of Gold At Incident Energy 44 Gev
Melyan, Elmira
Gold targets were irradiated by 4.4GeV deuteron beam at Nuclotron in the Joint Institute for Nuclear Research in Dubna, Russia. Residual nuclei were formed at ground and isomeric states from the interaction of deuteron and gold target, which have been measured and investigated by the induced-activity method. Cross sections of ground and isomeric states were obtained with corresponding isomer ratios of nuclides formed by the reaction as a result of this study.

The O-18(p, alpha)N-15 reaction is of great importance in several astrophysical scenarios, as it influences the production of key isotopes such as F-19, O-18 and N-15. In this work, a high accuracy O-18(p, alpha) N-15 reaction rate is proposed, based on the simultaneous fit of direct measurements and of the results of a new Trojan Horse experiment. In particular, we have focused on the study of the broad 660 keV 1/2(+) resonance. Since Gamma similar to 100 - 300 keV, it strongly influences the nearly-zero-energy region of the cross section by means of the low-energy tail of the resonant contribution and dominates the cross section at higher energies. Here we provide a factor of 2 larger reaction rate above T similar to 0.510(9) K based over our new improved determination of its resonance parameters.
