Download or read book Improved Limit on the Mass Of Nu Sub E from the Beta Decay of Molecular Tritium written by and published by . This book was released on 1990 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report a new upper limit of 13.4 eV (95% confidence level) on the mass of the electron antineutrino from a study of the shape of the beta spectrum of free molecular tritium. This result appears to be inconsistent with a reported value for the mass of 26(5) eV. The electron neutrino is evidently not massive enough to close the universe by itself. 21 refs., 1 fig., 2 tabs.

Available in PDF, EPUB and Kindle. Book excerpt: The beta spectrum of the decay of free molecular tritium has been accurately measured in order to search for a finite anti nu/sub e/ mass. The final state effects in molecular tritium are accurately known and the data thus yield an essentially model independent upper limit of 29 eV on the anti nu/sub e/ mass at the 95% confidence level. 17 refs., 4 figs., 1 tab.
Download or read book Limit on Anti Nu sub E Mass from Free Molecular Tritium Beta Decay written by and published by . This book was released on 1987 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The beta spectrum of free molecular tritium has been measured in order to search for a finite electron antineutrino mass. The final-state effects in molecular tritium are accurately known and the data thus yield an essentially model-independent upper limit of 27 eV on the anti .nu./sub e/ mass at the 95% confidence level. This limit is dominated by the statistics obtained in the data sets. Optimization of the experimental apparatus is underway and an ultimate sensitivity of 10 eV is expected. 19 refs., 2 figs., 1 tab.

Download or read book Los Alamos Experiment on the Beta Decay of Free Molecular Tritium written by and published by . This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The beta spectrum of the decay of free molecular tritium has been accurately measured in order to search for a finite anti nu/sub e/ mass. The betas originating from the decay of free tritium molecules in a differentially pumped source region were momentum analyzed in a toroidal beta spectrometer with 36-eV resolution. The final state effects in molecular tritium are accurately known and the data thus allow us to set an upper limit of 29.3 eV on the anti nu/sub e/ mass at the 95% confidence level.
Download or read book Progress Report on the Los Alamos Tritium Beta Decay Experiment written by and published by . This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements near the endpoint of the tritium beta-decay spectrum using a gaseous molecular tritium source yield an essentially model-independent upper limit of 27 eV on the /ovr .nu.//sub e/ mass at the 95% confidence level. Since demonstrating from this initial measurement the successful operation of a gaseous source based system, most of our effort has been concentrated towards the upgrade and optimization of the experimental apparatus. The emphasis of this work has been to eliminate or further reduce effects that generate systematic errors. Based on realistic projections from our initial measurement, an ultimate sensitivity to neutrino mass of 10 eV is expected. 12 refs., 1 fig.

Download or read book Frontiers in Physics 2017 2018 Editor s Choice written by Thomas Beyer and published by Frontiers Media SA. This book was released on 2019-02-22 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Launched in 2013, Frontiers in Physics consists of 18 specialties covering all areas of research in physics. With over 500 published manuscripts, the journal is now indexed in SCIE with the first impact factor coming in 2019. Frontiers in Physics aims to become the largest and most cited open access multidisciplinary physics journal. This eBook collects what the Specialty Chief Editors of the journal believed were the most interesting manuscripts published over the past two years. It is a nice collection, which will offer the reader the chance to have a quick overview of the specialties of the journal and offer a glimpse into the state of the art of physics. We must confess that it has been quite challenging to select only one article per specialty section given the many important manuscripts published by the journal in 2017 and 2018. We invite our reader to have a look at the journal homepage and browse what we have published so far. It includes articles on topics very different from each other, written by both early career scientists and well-known researchers, ranging from the indisputable advance of the field to the more bold. We hope you enjoy reading our first edition of the Frontiers in Physics Editor's Choice eBook! Professor Alex Hansen (Field Chief Editor) and Dr Claudio Bogazzi (Journal Manager)

This book was released on 2007-10-29 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the properties of the neutrino is one of the most pursued goals of physics. The series of MEDEX Conferences, which started ten years ago, is devoted to the update of the experimental and theoretical information related to the nuclear double beta decay, which is the process that may, if observed, be the tool to answer the fundamental questions related to the neutrino mass scale. MEDEX is a unique forum for theoreticians and experimentalists active in the field.
