Available in PDF, EPUB and Kindle. Book excerpt: The document is a continuation of the work started under Contract 61(052)-857. The aim is to determine the angular correlation constant, and hence, the coupling constant ratio C sub A/C sub V, in neutron beta decay by measuring the shape of the proton recoil spectrum. Further preliminary investigations were done concerning the effect of neutron motion and finite spectrometer resolution upon the spectrum, on the optimization of the measurement cycle, and on the appearance of surface charges under electron irradiation. The beam tube insert and the vacuum system have been assembled and tested. The magnetic shielding inside the beam tube was tested. The proton test source has been finished. The proton detector has been tested, and it was possible to reduce the background counting rate to a sufficiently low value. The control and data output system has been finished and tested. An evaluation of coupling constants in beta decay using published data was done by means of a computer program. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Precision measurements in free neutron beta decay serve to determine the coupling constants of beta decay, and offer several stringent tests of the standard model. This study describes the free neutron beta decay program planned for the Fundamental Physics Beamline at the Spallation Neutron Source at Oak Ridge National Laboratory, and finally puts it into the context of other recent and planned measurements of neutron beta decay observables.

This book was released on 2014 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: The free neutron beta decay correlation A0 between neutron polarization and electron emission direction provides the strongest constraint on the ratio [lambda] = g[sub-A]/g[sub-V] of the Axial-vector to Vector coupling constants in Weak decay. In conjunction with the CKM Matrix element V[sub-ud] and the neutron lifetime [tau sub-n], [lambda] provides a test of Standard Model assumptions for the Weak interaction. Leading high-precision measurements of A0 and [tau sub-n] in the 1995-2005 time period showed discrepancies with prior measurements and Standard Model predictions for the relationship between [lambda], [tau sub-n], and V[sub-ud]. The UCNA experiment was developed to measure A0 from decay of polarized ultracold neutrons (UCN), providing a complementary determination of [lambda] with different systematic uncertainties from prior cold neutron beam experiments. This dissertation describes analysis of the dataset collected by UCNA in 2010, with emphasis on detector response calibrations and systematics. The UCNA measurement is placed in the context of the most recent [tau sub-n] results and cold neutron A0 experiments.

Available in PDF, EPUB and Kindle. Book excerpt: The ENAM2001 Conference was held on July 2-7, 2001 at the Rantasipi Aulanko Hotel in Hameenlinna in southern Finland. The conference was organized by the Department of Physics and the Accelerator Laboratory of the University of Jyvaskyla with support from the Physics Departments of the Universities of Helsinki and Turku. This conference, Exotic Nuclei and Atomic Masses has now gained the status of a major nuclear physics serial conference. The previous conference was held in Bellaire, Michigan, USA. The conference was first held in 1967 in Lysekil, Sweden, then entitled Conference on Nuclei Far from Stability. ENAM2001 welcomed 270 participants from 34 countries, including 17 accompanying per sons. The content of the program was selected based on the advice of the International Advisory Committee. The Committee members read and considered 253 submitted abstracts in selecting oral contributions. During the conference week 76 invited and oral talks were given. The rest of the contributions were presented in dedicated poster sessions. Many thanks go to the speakers of oral and poster presentations for their enthusiasm and for the high quality of their work which demonstrated the liveliness of the field. Participation in the lectures was high and contributions from the audience were important towards the success of this conference. The organizers would like to especially thank Cary Davids of Argonne National Laboratory for his comprehensive summary talk, which is also included in these Proceedings.

Available in PDF, EPUB and Kindle. Book excerpt: We have measured the mbox beta - nu correlation coefficient, a_beta nu, in 21Na using a laser-trapped sample. We measure the energyspectrum of the recoil nuclei by measuring their time-of-flight incoincidence with the atomic electrons shaken off in beta decay. Highdetectionefficiency of these low-energy electrons allows good countingstatistics, even with low trap density, which suppresses thephotoassociation of molecular sodium, which can cause a large systematicerror. Our measurement, with a 1 percent fractional uncertainty, agreeswith the Standard Model prediction but disagrees with our previousmeasurement which was susceptible to error introduced by molecularsodium. We summarize precise measurements of a_ beta nu and theirconsequences for searches for Beyond Standard Model scalar and tensorcurrent couplings.
