This book was released on 1993 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the accomplishments of the project S̀̀tudies of nuclear reactions at very low energies̀̀. This project was undertaken in 1987 and completed in 1993. All but one of the major objectives of this study have been accomplished. Specifically the authors have completed their investigation of the (p,?) on light nuclei, a study of the Oppenheimer-Phillips effect, a measurements of the astrophysically interesting reaction D(?,?)6Li at low energies and an extension of the reaction D(d,?)4He to lower energies than previously observed. Preliminary investigation of te reaction 7Li(3He, p)9Be was begun and is continuing under a separate DOE grant. In addition to these tasks, they have completed some very interesting projects which were not included in the original proposal. These include a study of the (d,?) reactions on 6Li, 7Li and 1°B and an investigation of the possibility of observing terrestrial antineutrinos from the beta decay chains of U and Th as a diagnostic of terrestrial heat flow.

Book excerpt: A major accomplishment of this project in the past year is the completion of a fairly comprehensive paper describing the survey of radiative capture reactions of protons on light nuclei at low energies. In addition we have completed a preliminary set of measurements of (d, p)/(d, [alpha]) cross section ratios on the charge symmetric nuclei 6Li and 1°B as a test of the Oppenheimer-Phillips effect. While the 6Li data remain inconclusive, the 1°B data show solid evidence for the Oppenheimer-Phillips enhancement of the (d, p) reaction relative to the (d, [alpha]) reaction for deuteron bombarding energies below about 100 keV. We have continued our investigation of fusion reaction products from deuterium-metal systems at room temperatures with the startling observation of intense burst of energetic charged particles from deuterium gas loaded thin titaium foils subject to non-equilibrium thermal and electrical conditions. We have completed two projects involving the application of the low energy particle accelerator to material science problems; firstly a study of the transformation of crystalline to amorphous Fe-Zr systems by proton irradiation and secondly the effects of ion bombardment on the critical temperature of YBCO high-temperature superconductors. Finally we have made progress in several instrumentation projects which will be used in some of the up-coming measurements of nuclear cross sections at very low energies.

Book excerpt: We summarize the accomplishments of the first full year's operation of the Colorado School of Mines low energy nuclear physics project utilizing the General Ionex Model 1545 low energy, high current particle accelerator. The projects which we have completed which were explicity included in the original contract proposal include the measurement of the gamma ray branching ratios of the p + 6Li, p + 7Li, and p + 11B reactions as well as the absolute yield of the reaction 9Be(p, .gamma.)1°B between proton laboratory energies of about 40 to 180 keV. in the course of these measurements we have demonstrated the associated gamma ray technique for Germanium detector efficiency calibration at gamma ray energies up to 12 MeV using very low energy proton beams. We have, in addition, pursued a fairly comprehensive investigation of an extremely interesting and totally surprising phenomenon in which we see a yield of the d-d fusion reaction during bombardment of deuterated polyethylene by light to medium ion and molecular beams which is greatly enhanced over the yield expected from a straight-forward secondary ion reaction calculation. This enhanced yield is seen to correlate with the beam line pressure, suggesting target heating effects to be the source of the enhancement. In conjunction with a parallel contract with the Applied Plasma Physics Program in the DOE Office of Fusion Energy, we have developed an eight channel fast gamma ray spectrometer utilizing the fluorocarbon liquid scintillator NE226. The system has been operated at total gamma ray count rates up to 2.5 MHz with good energy resolution and with no measured dead-time and acceptable levels of pulse pile-up.
